That rabbit is awesome! Definitely my favorite part. The girl is great too, and the robot seems like he will be good, once he is finished. I suggest looking at Ptoings stuff on pixeljoint, he has a great way of rendering robots.
It still seems pretty early, so my crits are basically on what I think you should work on.
- The angle and style of the smashing things seems off. The tileset has an interesting type of style of these big squares, very blocky and reveling in it's pixelness, then the smashers are so smooth, too smooth. It's like every corner and edge has been smoothed up. Tr and blockify them and move away from that boring pure grey ramp.
- I don't think the smashers need to have the same angle as the tiles, in fact I think if they were direct side views it would look better.
- I like the style of the tiles, with the big pixels and all. I'd just take it a little farther, add in significantly more variation. Right now the fact that it repeats every single tile is really obvious.
Any keep up the good work. And seriously, I love that rabbit.
