A very well done figure. I have a few little tweaks you may consider for this and any future figures.
Either fold the handles in on the water bottle cup or just turn the cup around.
Dump the stock DML peg on the water bottle strap, add a small buckle and glue the strap down.
Do a dirty wash on the belt buckle.
Paint the fasteners on the MP40 pouches a silver, aluminum or light gray color. They may or may not have started life black in color but didn't stay that way long.
