Wow, thanks. I'll make sure to make note of this.

I think you have a lot of unnecessary colours in the image. For example, the two midtone greens on the leaves are barely distinguishable zoomed out. Also, you often don't need new, separate colours for AA, more often than not you can use colours already in the image, and only need new colours in a few rare situation.

You neglected to AA the eyes, so they don't quite fit with the rest of the image. Also, some of your AA around the big light circles around the eyes feels lighter than the rest of the line, so your colour choices might not be entirely appropriate.

The little wings also have some strange AAing going on, it looks more like you're randomly colouring the lines rather than AAing.

The AA on the big form shadow, spanning from the side onto the belly has a couple of problems: 1. On the belly, the AA hugs the shadow exactly, creating unseemly banding that actually makes the transition seem blockier rather than smoother. 2. The AA colour on the brown part is barely distinguishable from the lighter brown so it doesn't smooth the transition. The two main colours there are so similar that you don't really need AA there at all.
