Kitbashed EM4 space orcs - and orkish work in progress

A couple of months ago, I kitbashed some EM4 Fantasy Warriors orcs into space orcs through the tried-and-tested route of "stick a gun on a fantasy figure and call it a spaceman". I painted these up for a game in June but forgot to record them. There are many more to come. 

Since playing One Page Rules: Grimdark Future then, I've been putting together some multi-based orks for that game and similar sci-fi ones (e.g. Xenos Rampant). I like the 3/2/1 basing system that some people use for the Rampant games, and I've realised that it would work just fine in Grimdark Future. Here are some WIP bases, both for primitive orks ("berserkers" in GF) and more tech-savvy ones:

I really like this style of basing and might extend it to include some 4s and 5s. For games that involve large groups of figures, it makes movement so much easier and avoids the unsightly spectacle of lots of individually based figures crammed together and falling over each other on the table.
