I live in the Netherlands, the last time we got sun and rain here was two months ago, for the rest it's mostly rain.
The drawing is very nice overall, the rain looks good and the way you made her hair (mane?) look wet is nice, though I think it would hang down more if it gets soaked.
Her elbow seems a bit strange though, whenever I stretch my arms out, my fingers face away from me, with my elbows a bit bended (I over stretch my joints though, so my arms are not the best example XD). But the fact that her elbow joint is behind her hair makes it a bit harder to see, so I could be misjudging.
Overall, the drawing is very nice, I definitely like the brown, almost sepia, colours you used.
