The absolute number one cause of rejection of DD suggestions for most Artisan Craft CVs is poor photography. There is nothing worse than seeing an otherwise brilliant piece ruined by a dodgy photo. But even beyond DD acceptance, if you want to people on dA to be able to appreciate your skill you need to be able to show your work off to advantage.
Sometimes I'll tell a self-suggester that I can't feature their work because of the quality of the photography and they'll inevitably reply, "Oh, I'll have to get a better camera."
Repeat after me: the tools never make the artist.
You don't need a $9000 sewing machine to stitch a dress, you don't need a $1000 stand mixer to bake a cake, and you similarly don't need a top of the range SLR to take a brilliant photograph. It's all in how you take the photo.
