Looking good, Jack! The '-61 is my favorite plane of all time and it looks like you did it some justice. I know that Monogram kit is a challenge but it can be built into a good looking model as you just demonstrated. It's a good kit to hone your modeling skills for sure (puttying, sanding, weathering, etc).
I've built eight of those Black Widows so far. In my stash, I have the Great Wall Hobby P-61. I heard it was a fairly decent kit so I can't wait to give that one a try. It's going to be weird having a P-61 kit where the canopy actually fits well! LOL!
