I mainly make layouts, but I thought I'd try making a signature. I've made signatures before, but I used the same techniques I used on my layouts, so it didn't really work. xP
Wow, for a first sig that's great!
Good composition, simplistic and clean, good colors.
Blending could be a little better, maybe instead of erasing put some splatter/effects over the part you want to blend. Also that thick bar and the text could change.
