beautiful technique dude.
This last one looks like it could be improved pretty simply, just by separating different elements into foreground, middleground and background. So far most of the environment is a bit messy and seems to blend too much all around. For example, the big tree on the right and the background behind it are too similar in value. It flattens things out. Keep it in mind for the next one, if you're not going to work on that one anymore. Cheers!
Long time no update again. Been working on Oils - Only sharing one of the more successful pieces to come out of it. Done from life in 3/4 days
Thanks for the crit, I started off with pretty well defined value ranges but I guess somewhere in the middle of the painting they got a bit messed up. Shall try to keep things more defined next time.
