Please don't submit pieces.
This is very nice. I really like it, and yet it's a nice picture, but it's a pointless animation. You could submit it (the pic) to the Art Portal and it'd do well. But as far as being in the animation Portal, it's really lacking anything it needs in order to be here. Even if it had music, an occasional bird chip or fly-by, rain, deer walking thru, SOMETHING else to it, then it'd make a nice screen-saver-like relaxing piece.
See "MLP Rarity bath time" in my favorites or cut & paste this: http://www.newgroun ds.com/portal/view/582959 (remove the space).
It's a picture for the most part, until you realize that there are things going on all over the place. When combined with the relaxing music, you get a wonderful relaxing piece.
This sweet picture has the beginnings of something cool and relaxing like that, but for now, it's just a picture, and this isn't the Art Portal. It's the animation Portal, and this really doesn't have any.
