Now I am posting this to show my own work off! Several years ago I had a young man ask me if I could make a picture look like his drawing.
The first pic is his drawing and the second one is a car that I picked and made the changes like his drawing (now everything you see that I changed I made in photoshop with one exception that is the vent on the hood, I took the idea off a viper but I still made it) The third pic is the finished product. it is a 3d paint job. Again everything you see I did with photoshop including the painting.
I had some where 18 hours in it. NOW I better not find anyone using any of my work on there chop!!!!!!! If you do I will be on you like white on rice! Just kidding! I consider it an honor when someone thinks my work is good enough to use it on theres!!!
The reason I dont do stuff like that any more I just dont have the time to do it!!
