First off. Welcome ^_^
Personally I prefer the second signature - however they're both quite wide for signatures in my opinion.
In the second, may I ask what the hell the white thing is :lol:
The stars in both do not seem to be bright enough. Upping the contrast may resolve that.
I would also lower the opacity on the text since it pokes out a lot for mine.
GJ for your first sigs - your skill through making banners has improved the quality of your firsts in comparsion to a lot of people who just start using photoshop for signatures. It shows.
