Drawing different body types is my weakness. I can kind of figure it out if it's "that guy is burly, this guy is skinny, that guy is chubby, this guy is toned" but if it's more detailed like "this guy is a cyclist, that guy is a wrestler, this guy and that guy are overweight but they have different fat distributions" kind of stuff it is very hard.
You figure it out well.
(And consistency. I feel like my character's bodies change whenever I draw them. Though, for some, I have an excuse of them being non-human/have body-altering magic/simply gain or lose weight because only enlightened writers do world-building to work around and excuse their sloppiness)
Another trope I like is when some characters have goofy sleepwear or underwear
like the strawberry underwear here or that stupid sleeping hat Naruto uses.
Thread tax
I draw a new outfit for him
I want to try some design asymmetry, but was reminded the character actually has his right arm in the process of healing, so I draw something resembling a support.

I suck at design, but I like playing dress up doll with my characters
I didn't draw much last three months, but I did a crude sketch of the healer three

The pointy teeth is actually the remnant of transformation, but it fits him nicely I keep it.
