1st exercise so far. I'll do the rest too, but it might take me some time :)

I had some difficulties with the white gouache. I'm not getting it as white I'd like to, and it always seems more light gray. I think it's because too much water, but how to make it less watered but still get the flow of paint and not sticky clumps? 

I really love the sun reflecting from the water, this is the best what I've achieved so far with water themed paintings.
