A few closeups, warts and all (actually it's mainly dust) as inspiration/warning to fellow aspiring faceuppers:
I'm pretty happy with the size and general placement of the Bratz' eyes, and the pupils are at least looking in almost the same direction. Steffi Love's eyes are way too small and really different in size, but I like the shape and I'll try to make something similar next time.
Steffi looks okay from a distance, but up close... not so much. I never bothered with the eyebrows.
At some point I lost concentration and began trying every technique at once, which is never a good idea. If it's not too cold to work by the open window tomorrow, I'll wipe this and start over with a clean slate. I'd like to practice both the "many tiny lines method" and the "big dry blush brush" a bit, but I'll try to do one at a time this go. I should get another head too, so I can cut down on the wait between coats a bit.
The main problem is I'm still laying on the paint too heavy, which results in a lumpy, uneven surface that it's impossible to paint straight, even lines and brush strokes on top of.
I'm not sure about the best way to dilute the paint: the liquid acrylic medium I bought earlier is actually thicker than the Liquitex Ink!; the flow enhancer says to mix it in the water, but I'm not sure you can just substitute it; and several tutorials warn against using too much water since apparently that can make the paint flake later. Mostly I'm worried about getting comfortable with a method, then finding out about some hidden pitfall and having to relearn everything from the bottom up... And as usual, I end up overthinking it instead of just getting in there and trying stuff out! :)
I do need a smaller brush, or at least another 15/0 (the smallest they had) and cut it down some more. The tip on this one looks bent and frayed already, though, so either I'm being too rough or the quality is crap. Also a proper lamp, and I think a magnifier would be REALLY useful - I keep taking off my glasses to paint a few strokes, then putting them back on so I can see to dip and wipe the brush properly... X-/ (That's me, squinting.) Time for another trip to IKEA...
