Welcome to the forum!
Very nice work here, I love the freehand on the diorama bases, and the miniatures themselves look good, just need more photos
My $0.02: Personally I like the freehand space marine helmet you painted. I think people forget sometimes that for a piece of freehand to look like "part of the scene" sometimes means
it should *not* look like a perfect 3d rendering, but more like something that someone in that universe would have painted.
So the stylised look of the helmet is pretty bloody great, if you ask me.
