I really like the overall mood of this! The water seems really bright / saturated to me, but I don't know if that's on purpose or not. Also in the middle area the bricks seem to blend in with the background a bit and are kinda hard to see. The color palette is nice and the plants / creature look really cool :).
Ok maybe I try something more flashy , I am really bad to choose colors ahah
For me the colours are really boring, expect the green. Other than that, quite cool piece. :)
Thanks guys , yes the water is satured but it is on purpose.
The colors was stolen and the world is in black and white , so I wanted that the few colors left be more flashy.
