*Bash Bash* No, really.. a lot of people that are new to photoshop, are like.. "shit, bad critics, those fuckers, imma kill them, i pwn in PS ffs"
Bad comments/critics about your work, is good comments/critics, it just shows what you lack, and should work on, and of course, that makes you better, it might take a while, it usually does that to everyone before they get a hang of it, but be sure to read some tuts and stuff, and you WILL get better, believe me..
