This is just great. I´m a big fan, and I can almost hear his music with this pic. Can I ask you something? How do you do the hair? I´ve made my own tribute to some bassist, but I can´t get a good effect with the hair... Any advice??
Try to make big shapes with hard brush and then use small size soft brush with shape dynamics for details and single hairs. And then soft brush another time in airbrush mode for the light effects. Use a texture brush with natural feel can help you, but is not essential.I hope this helps you.
