I don't have a lot of my really old stuff anymore (at least not the crappy stuff) so a before doesn't work too well. Here's a few (in chronilogical (sp?) order) though.
Rakim sig.
There was a few things I did here. A rough colourization of a black and white pic. I got some decent colour composition going. The font ended up working well too. And I nailed "grunge" here.
Hakim Warrick sig
The big thing here was a whole 'I don't have to use 20 different layers of downloaded brushes to make a sig look good' realization. Simple can be just as effective.
Aftermath sig.
I did this as a request and it was one of the first times I used nothing but my brushes and defaults to make a sig. Now I only very occaisionally use downloaded brushes (for fractals and I use some 'scratch' brushes I have that are amazing.) The 'boxes' turned out well and I also used some photo effects that weren't the simple duplicate, blur, overlay that I waaaay overused. I don't think I've done that blur/overlay thing for quite a while now.
