Wow, it looks totally amazing! I love your colour palette man, and the high detail in the foreground contrasting with the simpler BG is pretty cool actually. Wouldn't have thought it would work so well!
I'm definitely interested in seeing more of your progress on this / more of your art. Sorry I can't offer any helpful advice, but I feel like I'm learning from you. I suck at environments, or at least getting colours to harmonize well together :/
Awesome stuff! x
