Great job on this monster! It looks like a chore to fit that in the display case! That gun is massive!
I agree--good call on the placement of the cupola. And the figures look fine---figure painting takes a lot of practice and a critical eye. Time will make you better at it if you critically and honestly critique yourself.
It's cool that you put them in in the first place.
The finishing is really nicely done. Weathering and camo all look superb!
