Spanish Republican Air Force: a couple of additional aircraft

I painted up this pair of planes a while ago for my Spanish Civil War solo campaign thing but thought I'd post them: a Dewoitine D.371 and a Polikarpov I-15 from Heroics & Ros.

Sesquiplanes and Biplanes are a little challenging to put together but who would one be to refuse a challenge?

Also, I had fun with the camo on a GHQ Soviet tank I got in a sample pack.
I think it's a T-90. Happy to be corrected. I added a tank commander as I'd lost the hatch. He's a Heroics & Ros Soviet infantry dude cut in half.
