About the sprite. I think that it's a pretty well made sprite. You should improve the arms a little bit, and maybe use it.
For the flowers, maybe a darker shade of blue? And the wild grass of Lost Forest should match up with the palettes you've used for the trees. So I suggest changing the palettes of the wild grass, with another grass tile and same behavior byte. Everything else looks really awesome.
I can't wait to see some scripts. I hope you update as soon as I post this. >:U
