First photoshop

This is my first photoshop picture. I gotta say, I don't understand or know how to use the tools yet, and it sure takes a long time to do anything, but it does really good coloring. x3

Oh, yeah, I would like to know if I did well, if there were things I could have done better, and your opinion of my photoshop pictures compared to my Corel Painter Essentials, if it's not too much of anyone's time.
