Hey there! :3

Firstly, terrain. I really like it! It has nice variation and a great palette.
I think the only thing it's missing is atmosphere. You could add some grass/wheat patches/pumpkins/melons blah blah. A water area somewhere would also be nice - like a large waterfall or something in the middle? :o

Secondly, organics. I really do love your organics! The palettes are super cool and totally original. I would like to see some more, however! Some more small trees around will also add to the atmosphere! And the only constructive criticism I have for the one tree at the very top of the plot (on the floating island) is that it needs more roots! I also love (what I assume is) the phoenix! Loving your palette choices in everything :3

Lastly, structure. You have none, and you definitely need some on this plot before you rank! Towers/houses would be super cool.

Good luck!
