thank you! i definitely agree with all your points.
there is some shading on the face, but it's very slight, i think i need to make the black a little more grey & saturated. and the bag is meant to be a flat circle, i always tend towards that ball-like shading as a default, so it's a really good idea for me to look at pictures. i always forget that refs are good and exist
this is what i'm going for, i'm almost thinking just a diagonal gradient would do the trick...
Channah has a bunch of bags in her commons shop, i was looking through those to make sure i wasn't making anything too similar to something that already exists. it's harder to find like a flat, taut fabric on mene, since it's a pretty unnatural shape for anything but this sort of bag or maybe a drum.
