Do you think my character’s topology is good or it could be dramatically improved?
It’s good, should deform well. Won’t work for realistic animation but it’ll work great for cartoonish animation 
Thanks for the reply; I’m making some characters based on Little Nightmares style, which I think may be pretty cartoony. This one which I posted serves as the male base model, he will be wearing clothes and hair, so only the head and the lower limbs will be really visible. I’m glad to hear that it’s a good topology
