I finally found my camera, so I took some better photos of the minis I modified.
The Archer with the Warhammer arms really turned out great, it's a mean looking machine with the missile racks and the big PPCs. The Warhammer with Archer arms...seems a little underdone; the arms still feel a little small but it works and the stats turned out nice enough.
I'm not happy with the size of the artillery piece I got for the Artillery 'Mech, it's just too small. A Shadowhawk's AC/5 is bigger than that is, so I'm going to replace them with larger guns - not sure just which yet, but it'll probably be oversized in the end.
The WHM with Archer arms is growing on me; they don't look nearly as gashed at the shoulder when you look at the mini. The flash from the camera and the shadow there really highlights how much it shows up; I'll probably end up greenstuffing it closed anyway. The arms don't look as undersized as they did before, I'm coming to like how it looks.
The Archer with Rifleman arms doesn't look as mean as the ARC-HAMMER, but it's still a good looking kitbash I think and it turned out pretty good. I might make another, this time off an ARC with LRM20s instead of LRM10s.
And of course the Rifleman with Archer arms, gotta tuck those ERPPCs into a tight fit which gives it a Thug look.
