I picked up some of the Cmon Wrath of kings Hadross pit fighters cheaply, and have painted a couple of test models. I am not sure about the scheme but will keep at it.
The bases don't show up well but I poured Mod Podge (the relief one) into an upside down Reaper plastic base. The product is a lot thinner than mod podge and it is hard to 'sculpt'. Will have a think about how to make these more dramatic.
