Wow, nice wall. I really like the colors, and the whole 'busy' look is really cool. I like it. The grass is pretty, I like how it's all colorful and I really like the snowy trees too. I'm not so sure I like the planets, not because they look bad, maybe you just used a little too many? And the resolution is a little weird too...
Over all, very nice work. keep it up!
