Grim - Nice job thus far. The only things that I would say are this:
Take you time with your figures. Don't get in such a hurry to BUILD them, but rather keep some things seperated until your done with painting. I ALWAYS keep my heads (and other flesh colored parts) off the model until they are done. This way, you don't get other paints on them. Plus its just easier to paint them that way.
Do a little more research in what clothing SF actually wear. From the dress, your figure should be placed in Afghanistan. Also from experience, while SF do wear some modified uniforms, they MUST wear a US uniform per Geneva. However, it's an easy fix. Just repaint your blue coat to match the trousers. Fixed.
That's all I can give for now .... However, I'll be following this one!
