At a loss for words, the fact you were able to keep things like the muscle structure and such still defined with that level of detailing is genuinely SUPER impressive. Like The fact I can see how the muscles still attach to the body while also having all those little intricacies is astounding. Honestly the only problem I can think of is that it doesn't quite feel like all the black shading really has a well defined and consistent light source. I feel the lack of like a consistent light source does hurt the readability slightly, like it can take a sec to see where the arm attaches since places like the tricep have less shading than the bicep even though the lighting looks like it's more in front than behind the creature for example vs the the leg which has more noticeable and defined shadow underneath that make it easier to spot at the base. Just my thoughts though, the level of detail and how it doesn't look like just a bunch of scribbles but actually planned out details with care put into their placement is REALLY good.
