It's very tacky.. You'd get some serious web-design props if were will still in mid-90s internet, but I just can't approve considering today's standards. In other words, what JK said. You're getting better though.
The reflection is very unnecessary, especially since several letters in your username are different letters when flipped upside-down. The "N" in that font, for example, looks like a "U" when flipped. Bad font choice to begin with, but the reflection shouldn't be there.
For the signature as a whole: Not necessarily a bad concept, but the execution is quite poor. An all-white background certainly wasn't the way to go.
Yeah, the letter reflection wasn't the right way to go, and reads like DIAWOUDBUCKK PO.
The Alien head's shadowing and reflections contrast a bit, and I don't know why you made the shadow a negative, it just reads weird.
Where is the render's right shoulder? I like it except for the render in general, but something needs to be there. Maybe a different render? If you moved the background to fit the rule of thirds you could get away without one.
Yeah, the entire sig seems very empty, and I don't really see the necessity of the big white boxes going across the entire thing. You've got to do a bit more with the space given.
about the shoulder thing that is his collar on his jacket it covers his shoulder.. and two i used a png and 3 i dono what else to do with the space lol
