This looks great! The only issue I can see is that the rain doesn't look natural. Usually there would be at least some variation in the direction of the raindrops, either that or the lines are too thick and clustered together in a way that makes them look more like lines instead of raindrops. It could just be me, but compared to the other piece of yours I saw, there's a big difference in the way the rain looks. Other than that, great work!
Perhaps not, but I just thought I'd bring it up as something for you to think about for the next time you include rain, is all. After all, that's how we improve - looking at what we've done and identifying what could be done better.
