Thanks for all your comments. The drops were done for real with watercolour paints, not colour added in Photoshop. I tried unwatered watercolours, which were very thick and vibrant, but didnt look like raindrops, and a bit too contrived, so I went for the watery look.
Composition is somewhat good, however I'd like to see more cropping in the bottom. Don't like the use of those colored drops, kind of shoehorn in my opinion. Just doesn't appeal to me. 6.
