Pinkie Pie in Paris!!

[Alliecat]

Cute! I like the choice of scene and she looks like she could be a fashionable Parisian girl.
I remember learning how to do stuff like that. I found a Photoshop project tutorial online, *not* for beginners, and did it anyway. It was fun and I learned to use some of the tools.
I've found that using dodge/burn around the edges of the part you paste in, softens and shadows them a bit, so they don't stand out as much and thus it looks more part-of-the-picture, and you could do the same under her feet to make shadows.
Keep at it and have fun
