the breasts seem a little deflated (maybe you were trying to make them on the smaller side?) and her fingers look kinda spiderlike but overall, pretty nice

the crystals should be a lot brighter to make them look as if they are shiny and a little see through. Perhaps add some white in there too.

saggy boobs and no hair?

 perhaps the burger should be a bit more faded, since it is being reflected

perhaps get rid of the black outline? Also, maybe lighten it up a little, the piece looks very dark and the colours are all kind of crammed into a very small space. Cool concept though, GO TURTLE DUDE!

That is probably the most disturbing thing I have ever seen in my life  The only thing that really bothers me is that one leg is red while the rest are black. Other than that, cool

Nice! Cute story too :D The only thing is that you need some antialiasing around the black edges. Otherwise, just get rid of them

Are those bars created by hand, pixel by pixel? They look suspiciously like they were texture filled...

You shoould wait for one robot to walk off the screen before the next comes in. Also, the colours of the robot don't exactly match the character. Is there a story behind this odd situation or is it just random? :D

 Cool concept but, as everyone said, needs work. The one thing that really bugs me is the neck. The left side of it looks like you just filled it in with the bucket tool  Other than that, pretty awesome
