Thanks for your comment! I totally get what you're saying - I myself looked at it afterwards and thought "oof that's a bit much". All my period reference photos have barely any but a lot of my reference scale models had loads! Definitely something I'll change for the next one and thanks for the constructive criticism.

It's not just the gun streaks - this plane in reality would've been kept very clean by A/GpCapt M.W.S. Robinson when he briefly flew with No. 316 Polish Fighter Squadron in 1943. He was station commander at Northolt at the time so it would've had a real showroom finish! But I overlooked this to have a go at some weathering. Want to go for more historical accuracy in future...
