Or a WIP for Black Widow, your call.
I am both frustrated and calmed by painting such a tiny model. I had a few frustrations with my skin paint coming out a bit splotchy but I am more or less happy with the skin. I am a bit frustrated with the eyes but they are passable as they are barely visible at that itty bitty size anyways.
I decided to go with a freehand zipper after touching up the body suit and will move onto the highlights and painting of the straps and armour patches. I am thinking of keeping her body suit black but making her holsters, belt and armour pieces (shoulder pads, knee pads, and greaves) a dark grey.
A short post, but hopefully inspires you to do what I have done: use a camera to double check your fiddly tiny bit painting.
