Wow! No new Mythos miniatures since November 2012!
I bought the Shadows of Brimstone swamp set a few months ago but never got around to painting any of them. The game itself seems like a great buy with tons of minis, cards, tiles and tokens; but, I have yet to play.
Be warned though, assembling the plastic minis was mind numbing. I have put together other plastic minis before, but for some reason these were pretty tough.
I used multiple layers of watered down white glue as an easy way to fill in the numerous gaps.
My approach to painting these was sort of a rough sketch concept, quick and dirty but with (hopefully) interesting blended colors. I quickly got the paint down and added highlights inks and powders.
For the effort I made, I'm pretty happy with the results so far.
