I spend 40 minutes on a sig, 30 minutes making it, 10 minutes touching it up, over 1 and 1/2 hourse is to much IMO. The render isnt good quality or its oversharpened. but i believe its better that your photofuckit sigs.
Its an improvement, you need to work on your blending ALOT.. I was the same way when i started though.. Another thing is the guy in that picture is reaaly oversharpened, or just low quality.. Also, i suggest working with a Wider canvas I didnt cover it all, but the others should be here soon.
Yes, please do. That was uneeded. Make the bright stuff appear on the other side. And make sure you save the render so you don't have the pixels. Unless you cut that yourself.
Just a pointer, never tell people how long it took to make something. Because some people take it as bragging. It's a good start, the render you used isn't great, but the positioning is pretty decent. There's some good tutorials around the internet, try your hand at one of those and you'll improve in no time.
