Good little scene. I like both composition and execution and my mind is changing and the more I look at the M-20 the more I like it too
. by the way, foliage looks quite convincing to me and that is one strong point here, I think.
Anyways, as I see you are working very fast, if I were you I would take little time to debug some little details here and there:
1> I would retouch the joint between the ends of the stone walls and the gound.
2> I would be very carefull to make sure all wheels touch the ground, a very delicate matter for a six wheeled vehicle on that narrow road I think.
3> I would NOT use drybrushing to highlight gound textures and believe there are some other better ways to finish it.
4> I would replace the tankers head by one head wearing infantry M1 helmet too for consistency.
And I think that is basically all. do not be dissapointed with me to be that picky with you, but you know I have high expectations of your work.
