I do. I'm doing 8 or so. Trying different things for each. There's where the set up time became an issue. Set up for 15 mins, paint half a dozen hands and faces (lets say 2 minutes per mini if being generous), wait to dry (15 mins), second coat (6 mins), teardown (15 mins).
Then I must be doing something wrong, because I'm following the whole "thin them down until it's the consistency of milk" strategy. Any thinner and it's basically a bad wash. Even with my thick coats, most of my results still show the base coat through raised areas like cheeks. Recently I got Army Painter barbarian flesh and it's at least a workable skin colour, unlike previous ones, but I still need to do a second coat.
That's basically what I'm doing.
Straps are proving tricky because they're in a recess so the "side of the brush" trick isn't working, but also raised so I don't think contrasts will work. I haven't tried them though. What's more, getting a smooth line is tricky due to the only brushes I have that are small enough holding so little paint that it takes several returns to the palette per strap, resulting in a line that is not smooth and looks terrible as a result.
A bunch are wearing goggles and I don't see any real way to paint them. It's like people who paint eyes. A dot would fill the entire lens, assuming it was possible to get there accurately.
