Almost finished painting up The Guru and two of his hired alien minions.
The Guru is unmodified, the minions are the Armed Minion bodies with the ape like Failed Experiment head.
The Minion head's neck diameter is smaller than the Failed Experiment head's, so I had to (hand) drill out the neck hole on the body. I also filed down the collar.
The problem with painting non human skin tones is trying to get a reasonable and 'realistic' look.
I am not completely convinced by the paint job. I have another nine Minions and heads on order, so I might try some other methods on those.
