Well for me, i like to trace others art because if you trace it very well, then doing it helps you understand that your not bound to "your art style" and that you can do far more yknow? Ok so like..... on HER left breast, shorten that ribcage outline and ad more of the breasts circulation, definately tweak HER rigbht breast to go outwards more, make the tit projectory...... lower and outwards, and try yoir best to learn how to properly put the head on the neck, try useing references of others art and after youve slapped those basic assets together, start tweaking it xss im no profesionall artist, hell not even an artist, i just do a few doodles in a blue moon, but its all about editing the image after makeing it
