It doesn't really have an OOB feeling about it.... Try tilting the frame backwards a bit by playing with the perspective. At the moment the ant just looks like its in front of the frame.
Another suggestion would be to have another background so he looks like he is going from one situation to another

Goodluck anyway.

EDIT: Oh wow a completely different image

That's a REALLY big ant!

u can also try adding shadow to the ant...it would make this looked more realistic.

Wouldn't want to come across that ant, it's huge. I would have picked a different color for the shadow instead of grey, possibly a darker part of the apple set to multiply.

Make the apple double the size and give ant shadow. Dark texture background vud suit. Nice idea. perspective to ant,, just give it a try..Carefully though.

Those were good suggestions author. Biggest thing it seems to lack though are the shadows.

Nicely done! One small suggestion that might help solidify this effect...try masking out the shadow away from the white frame. Allowing the white frame on the right side (bottom) to be seen all the way to the tire. See if this works.

i think that you should keep the tp in the image..good luck nice idea

good work
