Thank you for your comments, gents
Not a whole lot of progress this week since I've been busy with other stuff
The white paint pen makes it easier to color the stitches, but it is not a perfect solution and I'll have to go back to retouch some spots. I'm still not finished with the stitches because I can only do a few lines then I have to let the white paint dry before I can handle the figure (or else I get white spots on the black paint!).
The white stitches are really bright against the black but I'll add a grey-black wash over them later to tone them down a bit.
Punch list of things still remaining:
1) Finish painting the stitches white
2) Retouch some of the stitches with black
3) Retouch areas of the suit that got white paint on them because I touched wet paint and then handled the figure
4) Finish cutting the edges of the mask with black
5) Add a wash on the seams & stitches to tone down the white
6) Paint a couple of Future gloss coats on the suit
7) Put a semi-gloss coat on the boots
8) Glue the claws onto the fingertips and paint them dark gray
9) Make a display base
Getting closer!
Thanks for looking,
Joseph
