sky holes

I took a private lesson for the very first time in my life. Barbara guided me thru the process of choosing the right values, before and after the underpainting. We used some kind of turpenoid (the smell was quite intense we were getting all dizzy).
We spent more time talking about art than actually doing the stuff. So I left with this much done...





I spent the next day working on this. Note the detail of "sky holes" or breaking thru the red of the tree with a background color (either the sky blue or the mountain purple coming thru). This is an effect that I like a lot, noone ever thinks that one would first paint the tree to then add "sky" parts in between branches! but that's the only way to do it, or at least, the one that turns out more realistic.
