ouch....dude, what program do you use? A little tip from a fellow Gfx designer....Read lots of tutorials....LOTS of them. And do alot of mucking around with the plugins that come with your program. I use Photoshop, and before I released any work, I read photoshop tutorials just to learn little tips, tricks, and even learnt something new along the way.
Please....Practice more.
Also....Custom fonts look better than the default crap your using. Try
www.dafont.com for some cool fonts.
Good Luck, and if you want any tips on Photoshop, give me a yell
