I admire so much your work, it's really original, the colors are beautiful and they really "pass" a feeling, that's why I love your art : the way you use the colors, their importance, and the fact that you use watercolour too (I think that's really hard to manage to do something good with watercolour, so I have kind of a lot of respect for artists who use it ). So simply, this is AMAZING !
No I don't currently but it's straightforward. Basically sketch out the people shapes, paint around it first with a light layer of watercolours, wait for it to dry, paint the trees, wait to dry, paint the darker person in the middle, and then do splatters. :3
