The first ones text is a little strange not that it looks bad (its a little on the sharp side) but that it is Marmalade in blood and Marmalade usually brings oranges to mind call me crazy. the Street Fighter one is also a little on the sharp side the other one looks nice though i dotn know if it is supposed to be a user bar type idea or a small sig. But carry on read some tutorials in no time u will improve a lot. (My |Classy| tutorial is an easy way to do this) try it its simple there are other great and simple tutorials here also : )
Hmmm... They're not bad. I think you could be much better though. Try to work more on creating good flow with effect C4ds and better composition. The tuts here on GR's tut section can help this big time. Go check a few out here: http://www.gamerenders.com/forum/index.php?showforum=68 Then let's see some more! Keep workin'.
Do work on your background, text, render, and flow. I bet you're just a newbie in Photoshop. Well, all I can say is, try to explore more tutorials so that you'll be more aware what to do; once you equip yourself with the knowledge, you'll be a good digital artist. That's all I can say, good luck!
Sorry, I cannot bring myself to be a criminal. If I get Photoshop, I'll pay for it. For now, the GIMP works just as good.
