I think my only other piece of advice would be to make sure to respect the depth of the characters you're drawing. Folds take up space, taints/balls/cooch are sometimes gonna be buried in fat, stuff like that. Don't feel like you have to show everything per se if it isn't appropriate to the pose.
That's all I can think of though, you're going in good directions and your art has a lot of promise!
