It's been well over a year since I've even thought about touching photoshop, so here's my first creation in a year, its horrible..i know.
Yeah like xed said its not bad the dots around the neck and face make it look bad and the yellow area near the sun/star is a bit bright. Text is meh everyone is bad at text.
I think its really good , but I'm more of the grunge type , mabye you could try adding some smudge settings and over laying each layer to see what effect you get Good job keep it up
