Queen of the Woods

First I want to start with the fact it's made out of stock photos. It looks great, to be honest, to be made out of stock.

The drawn-on flowers, mane and tail- I don't know if you were going for that, but they just........don't look well. The marking on the hindquarters looks sloppy.

The birds-
They look nice, but I don't think using the same birds, just changing the colors doesn't look well. I'm no expert, but they just don't look realistic. Especially the green on the horse's mane and tail.

I actually think this is piece great, just.....a little messy. You did a great job editing it all together, though.
