certainly! observation is the first step!
honestly i dont put much stock into closing my lines. the fill topls make things easy, sure, but i usually just paint a layer behind the lineart and clip color to it. very smooth!
yeah! i think detailing the body is hardwe as you go lower lmao, i have such trouble with leaving too much space lookin all the same. bellybuttons, belts, waistbands- anything to break it up makes the form so much more cohesive (which seems odd to say i suppose but isnt really!)
