There are so many poses on Lioden, and its a huge undertaking to expect the artists to fit every decor to every pose, what Im suggesting would be a awesome solution until the artists can get to them.

The "Lion Dressing Room" would be similar to the Lion Wardrobe (or they could be combined on the same page) It would load your Lion in the same fashion but would also load all of your currently owned decors and backgrounds. But the best part is that the decors would be dragable, meaning you could move decors around the lion image to where you want them. This would fix pesky things like that bone crown almost fitting on your smilus or that cub decor that just doesnt look right levitating a few inches above the ground next to your posed lioness. This would also be useful for more unique designs.
What if you want that feather decor in your lions mane instead of his mouth of maybe you want a swarm of bees following you. Just load the lion in to the Dressing Room, click the decors, drag them to the desired location and save.
