I'm the kind to always ask but can we go bigger and I know what you mean, a lot of it's down to how people draw and distribute it. Even with differing levels of muscle you've got to keep the shape of the character in mind, for example, if you compare Otegine and Tonbokiri: no matter how bulky you decide to draw Otegine he has to have a narrower waist and a distinct T shape. Tonbo is stockier with a thick waist so you can make him as heavy set as you like so long as it's spread out and his powerful arms are kept.
What I look for most of all is a fleshy, soft pliable look, tense muscle bulges and the skin can be taut in places but relaxed is soft and has some give. The wrong side of that is making things into shiny balloons, or drawing rocky muscle definition that isn't made up, but doesn't connect up across the body and exists in a void. I hate when artists draw a flesh tone brick with a 12 pack attached to the front of it - the stomach doesn't build in isolation, there's wrap around muscles and the entire back working in tandem. There's also the kind who make pecs so malleable you can reach straight through them or squeeze them into cones; no, fuck no, this is not tid. I want a firm sofa cushion to rest my head on, not a barely functioning waterbed.
Here is a nice standard Gine with arm service. He's got enough chest to show through a shirt, but his tum is smooth, and his sides taper in pretty gently. Fits the official art, doesn't look hard for him to maintain.
This is what I'd call optimal pestle: https://a.uguu.se/xWNKW4b15Af0_66408904_p6.jpg
The narrow waist is exaggerated with a broad chest and poses that stick his rear out to give an hour glass look. Underneath he has full ab definition. It's a fantasy shape that'd look fucked in 3D.
And this is the same artist going full retard: https://a.uguu.se/SrquwMHSUBmo_whatamilookingatandmakeitgoaway.png
It's shiny, it's bloated, it doesn't look like it belongs because every contour is defined.
