Absolutely BRILLIANT !!!
As you iniste on suggestions, I would
1) add more shadows in the foldings of the coat to show more 3-D at distance
2) also shadow the pale yellow flowers in these folds, darker to make it sharper
3) darken also a few folds in the pant also to indicate 3-D (nta all !!)
4) Darken also the green geathers of the bird tail in the shadw side, to give them roundness = lloks too flat
5) Do small similar touches elsewhere too (bottom of boots, (like bottom of the tree in yellow/orange = more roundness)
I added red spots at locations touched....
