Lighten the shadows and make them less opaque. I'd remove the pink blob. I know it's supposed to be flowers, but it looks like a pink blob.
Also, the filter makes the castle look like a drawing. The basic concept is good, if a bit too saturated. The eagle/camel is well blended & believable.

Kind of looks like an illustration from an old Fairy Tale Book, after smoking crack. I'M JUST KIDDING.. but seriously, it looks really sharp.
If you have the original images (before the filter effect) place it under this layer and experiment with blending options to see what happens.
This is a mixed media contest, so this image is fine. Though I think the Lioness could be just a tad bit bigger so her ears break the cliff edge. She's looking more cat like instead of lion like. More little mushrooms might help to give them some purpose. They kind of look like the just plopped into the picture. Not a bad thing, but they are curious.
Good luck author.

Thanks for your criticism.

I removed the mushrooms but not because of placement but because I want to find different looking mushrooms. For the flowers, I wasn't really happy with it either. And yes I want it to be very bright and saturated like a bright sunny day, and sharp like a drawing.

I have some more source to add

Much improved, author!
Just try to lighten the shadows under the girl & beast, along with less opacity.

Beautiful and dreamy
