This is great, i wish i was that crab.

Thanks for your feedback :)
It was really not easy for me, that's the first time I'm trying to do that kind of challenge.
I'm happy to see you like it.
 

Woah. You've managed to get a ton of definition using only those four colours. Really like the contrast of straight lines of the city with the curves of the crab's shell, and respect that you've slanted some of the building lines.
