I had this exact same idea! You beat me to it...

Too blurry, rather than smoky/misty/ethereal. The stars also look a little flat and fakey.

The paint toss does not help this image.
It looks like the bird is pooping blood onto it. Not a happy joy experience for the bird...
Also, the flower shows a hard "cut and paste" edge.

The contrast is too dark, it's hard to see the nest from the tree, and you can't really make out the source image in the nest.
The mushrooms also are distracting, as they are the main visual vocal point, with the egg shell second. Your emphasis needs to be adjusted.

Very nice creation!

Nice concept, but you need to have more reflection of the statue in the water to match that of the bird.

The nose doesn't look right on the skull. Being soft tissue, it would have been the first thing to deteriorate...

Did you mean "Moses?"

The red triangular sections are too translucent, fading away from the rest of the image.
The curved and warped parts of the type ball on the left shows too obviously that you flipped the image - the type is backwards.
The composition is too "mirror perfect" in some areas, and too "non-mirrored" in others, most noiticeably in the lines above the crab claws. The one on the right isn't connected at the end, and is straighter than the one on the right. This inconsistency gives a poor technical visual effect, rather than being a creative part of the design.

The lighting on the reindeer looks weird, it doesn't match the source image. Also the fur on the hat has too much of a red cast, while the reindeer has a yellow cast, neither of which go well with the fully desaturated source. The apple just looks out of place with all the grime and cobwebs. It's too clean and fresh looking. The reindeer would have eaten it...

Great concept, but the green railings are distracting from the cool ghost girl.

Nice composition, but the color scheme is too disjointed. The owl is too "warm toned" for the picture, and the magenta bridge looks weird. Love the background tone, though.

The warp on the magnet on the LH side looks a bit too extreme, but the flower is very nice.

The green doesn't say "Air Force," and the numbers on each bird should be different. Otherwise, excellent concept!

The perspective is a bit off, making the helmet look crooked on her head, although that may have been your intention. She looks weird with no shoulders or arms, though.

The black hands don't make it look very hopeful, looks kind of scary. A bit of glow around it might help, too.

Great work!

It looks a bit empty on top. Too much negative space.

It's a good image, and does not portray ANY religion as good or evil. It is up to the viewer to see what they want to see...

Beautiful imagery, but the color tones don't match, making it look too "Cut and Paste," rather than a cohesive image. Perhaps a color cast filter over the entire piece would help.

It the misspelling deliberate?

Great mood and lighting, but the feet look a bit too rounded, and it looks kind of "pregnant." I think you should reshape and refine the body a bit more.

LOVE IT! Especially the crossed out "Pluto."
Simply Excellent. I hope you win with this one!

It would look more interesting if you could include some color.

Very cute, but the strawberry people look like they are floating. There are no shadows beneath them, and they are lit from beneath.
Image>Adjustments>Selective Color>Whites will help you tone the lighting to a darker red, and then you can paint in a bit of shadow.

Adorable concept. I would tone down the white of the eyes a bit, though. They are too bright. Otherwise, excellent!

Wonderfully creative and colorful. Well done!

Your light sources are all over the place. The bird is lit from the left, there is a sun on the right behind the rocks, the clouds are lit from above right, and the light rays coming from the nest aren't illuminating anything...Good concept, CLEAN lines, but you need to consolidate the lighting and make it consistent.

The light source on the grapes does not match the lighting on the floor, or the shadow beneath the grapes. All 3 need to be the same, lighter on the left, darker on the right. The floor is totally reversed, and the grapes show shadow beneath, not angled.

Other than that, though, BEAUTIFUL work on the grapes themselves!

The edges of the sphynx are a bit too ovbious, as if you outlined it. Also, the magnet head looks odd on the body - the perspecive is off, and it is noticeably lighter. Perhaps erase the bottom of the magnet's "shoulder" edge at reduced opacity, and darken the magnet just a wee bit more.
