Oohhh shiny. I love your stuff, especially your icons. ^ - ^
Criticism? Well, your little princess banner seems kind of busy, to be honest. Like, it has too much stuff going on in it. Sometimes, less is more. Maybe you could use less brushes next time? Just a suggestion.
Your many moons blend was blended pretty well, in the background at least, but the top of her head in the more forward pic (the one of her in the middle), it seems like the top of her head doesn't blend in very well. It might have needed to be erased a little more or something, because the sides of her hair fit in very well. But otherwise it's very pretty!
