my suggestion for paint....find two good colors that go well together, and have a color for trim and a color for base. Or you could just stain it. I also might put wheels on it to make it a little eaiser to move? You can always get wheels with little locks on the so it wont roll away hehe, also make sure you water proof it or a seal or somthing you never know when it might be out in the elments since this is somthing you could potentailly move with you places. Also for the saddle stand maybe cut a cold peice of carpet and cover it? Looks better and wont scratch up any tack.
Hope this helped!!
