Your inputs are valuable and construction and I'd like to thank you for them.  As you'll see on the site now when you upload art and animation you can check whether it's 3d or 2d.  Now when visitors are looking for 2d art, for example, they simply press the 2d button to see all 2d art/animation.  We didn't feel that it was necessary to have both a 2d and a 3d art and animation section, and we also felt that this solution would make it easy and helpful to all.  This capability has only been active for a week or so and seems to be working well for all, but we will keep an open mind  to creating 2 sections if it becomes obvious that our solution isn't the best.  Please stay tuned as we fine tune the site.
