Very nice! I really like the movement of the goldfish and the plants, this is a great start! I agree with a few people that there is a blurry/fuzzy look to the rock, but that is a very picky. I have had it up for about 30 minutes so far with no problems at all. Thank you.
(I get about 90fps with 3 fish and everything looks smooth and realistic, those tailfins are especially nice!)
