Hi Darko,
It shouldn't give more trouble working 1/16 compared to larger scale.
Maybe the head needs smaller tools but even then I had a lot of profit from the thermoclay ( sketching...waiting, try again,...thinners,polishing)
For the base I have a good scaledrawing reduced to 120 mm.
I found out it took me more trouble to make up folds than making up a face.
Also nice to have some spareparts ( 120 mm and 200 mm have lots of)
a lot of shaping was done by toothpick, moisted by thinner, brushed into shape ( I don't need to tell you this,..you are the polish-king) with another agent, painting medium by Talens.
Maybe the way of brushing ( and when) is interesting, at this stage the kind of fabric kan be determinated ( sharp folds, soft)
Don't overdo it. It's nice to see a section of folds were else is none, contrast.
I also liked to work partially ( which I did not before). First the pants, then upperbody ( like the order of putting on clothes).
for anything else, check Antonio's way of checking shapes, volumes first and enjoy the benefits of this sketchingclay.
for the hands...armature. Practice makes perfect, though hands are tricky.
But also here, even at this scale it's doable.
For the scalecheck it's always good to have a regular 1/16 figure in reach, especially for the face.
alle the best,
René
