Actually the title's a joke. From what I can see there is no downside. In the first 3 days after I posted my entry I had over 120 visits to inclined to ramble from people following the link for a better look, I got 3 very complimentary comments from other artists, who when following links back turned out to be very fine artists themselves, and praise from peers is always much appreciated. Finally I've got the enthusiasm to keep going.
So now I'm back to the sketch pad to think about "open".
