We now have a DeviantART group!
Popular artsite DeviantART has recently launched a new feature simply known as Groups, and I've taken the opportunity to make a Count Duckula one myself.
CastleDuckula via DAGroups
There, members can suggest favourites as well as submitting their own Count Duckula artwork, either into both the group and their own gallery or as an exclusive to the group. We do have rules that you may want to check out first, just to be on the safe side.
We're still in early days, but check us out sometime!
