Finished (´・ω・)ノ
It won't stand up, so getting it to stand on its own was incredibly difficult.
The wings were a real pain ( ；´Д｀)
I had plenty of time with this kit, so as long as I carefully crafted the wings and checked the D-spruce and neck properly, I don't think there'll be any problems.
If I'm not careful, the Twin Buster Rifle and wings will support it, so I need to make sure I leave enough time to finish the final step of getting it to stand on its own.
