The guy is handsome ^^ (I'm going off topic, blah~)
Anyway, I think the background is too blurred - is it sakura trees that are supposed to be in the background? I can't define between the petals and branches...The rain effect is nice, but you overdid it, I think you should let the rain be thicker but less in frequency. A little more variation in the rain would be nice too. Why are there 'brick' effects in the background anyway? Maybe by removing it, it will look better ^^ And lower your sig too *.*

Anyway, it's a good wall for your first - I like the colors, but not the composition of the background~ Keep improving! Good luck!
