LucR, yes, it may not be great for yamadori, but I think I can make it work.
Rorror, Yes, those in orange are branches that I could leave until I can get some new ones growing. There are several trees, and a few of them actually have some lower branches like the one shown in orange.
I will go back there and clear the snow out. I apologize for the quality, it was dusk and I had a pretty bad camera. I will get some pictures tomorrow maybe.
Also, I don't really mind having a upright formal bonsai, so I am not worried about no curve in the trunk.
