So here I have a step by step breakdown of how I painted Mash. I am not going to get to detailed with descriptions, it is basically drybrushing and washing. I think you should be able to click each pic to enlarge. Overall, I spend more time waiting for washes to dry than I do actually painting.
I would note that one pic came up missing, the first coat of yellow on the beard. Otherwise, i made a few touch ups off the record, but this is mostly it.
