I know they are similar but I only had one picture of Baron Davis and I did these sigs all in one day
Strike31. Those arent really that similar at all only the first 2 and its obvious2. He said he did them in ONE day not started today
Sometimes people leave sigs out of a topic on a forum like a sig gallery. I said similar because they are all Golden State mainly.
What program? I'd focus on improving your BGs right now. I suggest you go to deviantart.com and DL some better brush sets and look for tutorials to develop some techniques. These aren't too bad for a beginner.
