So reworked my concept boards once again. I think this is the last time for that, now I'll have to start work on some style frames which will be slightly similar to my concept boards. Yes if you're confused so am I by all these concept boards and style frames.
So went back to the drawing board and reworked my concept boards. Made the horizon line a bit more rounded in order to give them a more global feel and muted the underwater scene a bit more.
