I like your builds- nice work put into them. For the m10, I think the amount of dirt is fine. Everyone has their own artistic taste on that. I would've liked to see more dirt on the sandbags actually. The small chipping and tracks are also nicely done.
For the Sturmtiger - I think your zim came out terrific as did the camo.
The biggest thing for improvement I think would be to build more models to show
See ya at the campaign!
