First looks really cool, captures organic and robot quite well. Second has orgasmic plating, but looks really unfinished. Sort looks like just the background of a texture, missing the whole thing to it.

More!!!

Wow, i'm really glad that you kept going making textures. only problem is that i mostly think you put the eyes too high up D:
the organic feeling works really great tho, nice job :3

really creepy, it's amazing, but yeah the eyes are high :P

Totally got my new logo as my avatar now.

Needs some work to it though, well I think it does anyway.

i think i will start a new head soon i just need some more inspiration

im on this one hope you enjoy it

still a WIP

WIP 2:

Looks ok, but you might be able to use polar-coordinates to make the top a lot cleaner.

Whole concept is geat though, looking forward to the next version.

thanks for the tipp can you explain me the thing with the polar coordinates i always improvise the top.

made a running animation, i tried to make a gif file but it was acting really odd. its a new sprite for another game my friend and I are trying to make, this one have a lighting engine :3
also, feel free to make it to an animation if you can : P
