Since long time I can't submit anymore, because the artwork submission always expires. I don't see other artworks coming through Watch notifications either...
This is partially my bad. I've been away for dA forever due to work. I'm trying to become more active lately I've also been fiddling with the votes needed to approve as well. It should be down to one for members right now. One thing I can do if you are planning on trying to submit a lot is set you to contributors and you'll have automatic approval as well. Sorry about the inconvenience.
