Looks good! I really like the composition of this panel. For the rain, I think you could go with a bit larger strokes, but that really depends on what kind of rain you are going for. Right not, it's drizzle-like, I think, not super perceptible, but still, already evokes a rain day by the light and grey atmosphere even if someone miss the actual rain. But if you want to make sure people see the raindrops falling, yes, maybe a bit larger would be better.
