Hey, it's a start! Have you tried GIMP, I see some awesome edits by folks who use this and it's a free editing program. http://www.gimp.org/ Stick with it if you enjoy it, you'll get better, trust me.
Psp is not a limit, its how you use it.. ::) ive had around 6-7 years experience on the series.... but im still crap.. but i know some people that can make better graphics with psp than adobe photoshop
