I do not appreciate it when people steal others works without giving credit to those that made them. Especially when the work is my own.
The tech brushes used in that final image were made by me. You can check for yourselves at
www.greycobra.com > Downloads > Photoshop resources. The brushes are owned by me, and credit should be given likewise for their use.
On another note, the tut is nice. Not really original, but good explaining.
Your Signature and Ava are also full of my brushes.
