great work. You are your worst critic. What you see as a flaw most people will not even notice. I use aspen for white parts. The finish I use is equal parts - tung oil (tung oil finish because can't find pure tung oil often) matte or satin poly, and mineral spirits. I use this on all my projects 3-4 coats. it has a little shine but not bad. I don't like mine real glossy.
