I like the overall visual of these, particularly entry #14. You have chosen a picturesque tree, but we are interested in increasing productivity for industry, which means straight trees. Also, I would like to see a tree that is more clearly pine.
These are closer. #22 looks more like a spruce to me. #23 does look like a pine, but it is still a bit crooked. Lodgepole pine is the specific species we are interested in.
