What kind of tips do you want? eh.. actually I don’t have much special way to drawing. I used to feel that I’m less talented compared the others.
oh but if you want to know what I usually do ..
Anatomy drawings ?  It’s very helpful, also very boring.
But if you have some ‘necessary but dislike’ works to do instead of drawing, that will makes you have the most ecxiting time.
Uh,, It’s just kind of my limits on using computer software but I don’t use 'hand shaking correction’ or linework tools. I feel like that those useful tools will make me slave of computer. (just joke)
and I can give you some site for helping you, maybe you already know…
