Thoughtful weathering!
Do you have a 'before' pic to direct my untrained eye to your recent modifications?
I am just starting weathering too, definitely still on training wheels...
I like what you've done though; you must be relieved you got through it pretty successfully!
What i like is that it looks like you thought about the stories behind the scuffs and rust, and didn't just apply a formulaic, cookie cutter treatment.
Does it help to work on a vehicle that is closer to every day experience than a tank? Or maybe it makes it even more difficult because everyone can relate!
Hope you'll continue with more weathering on your next models...
It helps to remember that drawing and painting are more about how well you see and observe then how you hold the brush. You can always improve your technique, but much harder to learn how to really see and understand what is in front of you!
Cheers!
