Welcome to Watercolour Gallery. I agree with Vanessa; your third painting is delightful with that brilliant diffuse sun shining through the gap in the trees.
I like your first painting too of the night sky. 'Once in a blue (red?) moon'. But it can't be - there's thick cloud above. I think it is a very large red balloon. But this kind of painting defies analysis and does it matter? I just like it.
The second painting has a feeling of foreboding to it. I'm expecting a sudden flash of lightning to tear it apart!
