To give you a term of comparison I post here some pictures of my pre-airbrush German tanks.
|Pz IV H|
IMHO the overall result is not bad but clearly the effect with airbrush is much better...
Note also the handpainted Balkenkreutz and Numbers...
I Have a complete platoon of 5 Pz IV H
|Pz III N|
and 2 optional Pz III N
|Stug III G|
A platoon of 5 Stug
... and one of 5 Brummbar
.... too much work to repaint all of them !
