I'd suggest carrying on the black line across and under the spout...
The smaller lid is looking more like a stretched version of the top lid, and lastly the image looks like its all floating without a defined BG...

Not bad, try some shadows.

I don't see them, and you've created conflicting light sources by flipping the cup at right. The light on the others is from the left.

The perspective is off. The cups in the foreground would be much rounder top and bottom and you would see into the cups at the tops since they are below eye level.

You always have to think..."where is my light source?" even when collecting stock photos to use. I have turned down fantastic stock photos simple because the light source did not match with the piece I was working on. If you don't think where your shadows are CMYK46 will be the first to let you know! lol isn't that right Bob? :P
He does know what he is talking about.

you know what would be nice...is if you,
duplicated the cups
flipped vertically
Gaussian blur about 40%
drop opacity to 30%.
then you would have a nice reflective surface coming from your tiled counter. look sharp!

cool! now take the farthest cup reflection, and erase gradually. getting heavier with the eraser as you get closer to it. This one in the back would be less prominent then the others. Also gently erase the reflection where the bottoms meet the existing cup. I would say about same distance as your shadow.

Thanks I took care of and Thanks for the help.

Thanks!

Your corners are still too sharp on the 'cups' using the ellipse will create the correct shape, also the dark line at the top of the cup would also have a slight curve - following spacerangers advice regarding eye levels. Lastly take some time to clone out the repeating patterns you have on all the cups. (make the two front different to the one at the back)
