can I challenge you to draw something with your left hand? One of my classmates did this to me and I've been using my left hand ever since Now I draw with both hands and it feels amazing. Left hand for the sketch, right hand for the details.
it's so amazing, I'm not trying to brag here, but it really did wonder to my artwork! mainly in traditional media, because I can't actually see my hand while drawing digitally and it makes it harder. But if you use a cintiq it could be easier!
