I bought this mini about a year ago, just because I really like the sculpt. It’s a Reaper Miniature, sculpted by Tre Manor. From the overlarge hands and eyes, to the stout body and outrageous mustache, the figure just begged for a cartoonish paintjob, which I attempted with extreme contrast and bold, blocky coloring. The sword and other hardware are painted with NMM (that’s non-metallic metal – painted with shades of gray, not metallic paint).
I went ahead and gave him a magnetized large base insert, so he can be used for D&D. (I’ve done that for all of the fighter-type minis I’ve painted since 2011. It makes it easier to manage the movement grid when the fighter is subject to “Enlarge Person”, one of the best fighter buffs in the PHB, and thus often used.)
This was a really fun miniature to paint!
For the freehand on the shield, I did a Google Image search for “painted shield” and found a photo of a shield with a great-looking boar. I sketched it on paper with pencil, then blocked out the sketch into geometric shapes. I lightly painted those shapes onto the shield, and used them as a guide for freehand painting the outline of the boar. Then I filled in the large areas, finally adding the fine details at the end. Jen Haley describes this method on her website.
