Your (not so hated) Admin here. (I seem to have less hate notes for the past few months, I so guess you guys like me more now).
Just a few quickie notes and reminders:
1. Photo paint over
This group don't have a rule for photo paint over. I assume mostly because the merit of such method is still under debate and it's near impossible to prove. But here's my personal advice: Photo paintover is BAD for you. There're some submissions I know are photo paint over, others I suspect, and I think there're quite a lot I don't know. Coming from an fellow struggling artist, I urge you to stay away from this practice. It might be a quick way to produce good looking art (that's why industry people do it), but it'll not improve your skill. On the contrary, it'll get you to reply on photographs, and before you know it, you can't do anything without ready made photo.
So DON'T DO IT.
2. Be careful of which category you submit to.
Some times I decline works because they submit to the wrong category. So be mindful of that.
3. Use artist tape to make clean pretty edges of your drawing.
simply use the tape to tape the edge of the paper before you start, draw your heart out, and remove the tape at the end. you get nice clean edges.
4. Take better picture or buy a scanner.
A scanner is not that expensive. Buy one please, your art deserve that much.
A late happy 4th of July to all my American countrymen and happy weekend for the rest of the world.
