Instant Gratification is boring

[Terminal Devastation]

Yeah, I'm trying to learn how to make awesome level sprites like some of you guys, but I keep getting instant gratification for this sprite where ever I post it, and its not awesome yet though. I'm hoping you guys can give my the critique I'm looking for. I was going for a girly relucant look in case it helps.

If I may be so bold, can I get a side order of boxes showing where the errors are along with my heavy critique?
