i'd say #1 is anatomy
when i first started studying anatomy, even though there were times i really hated it, it also improves your work a LOT
i see youre using guidelines (which is awesome biggrin ) and dont ever stop using them until you believe you really have the placement of things NAILED DOWN
- something i see a lot of beginners do is use guidelines for a while, then stop later saying that they get how to place things (which isnt always the case, in fact it often isnt, even i still use them)
- it also makes it easier to spot anatomy/ pose/ perspective etc errors biggrin
while youre working on that, always try new poses and angles, that way you wont run into the problem of going through the situation of drawing a perfect front view, but alien looking back view of a person or something like that XD
other than that, everything else will come naturally biggrin linework, colouring, tone/ values, etc will come naturally with just practice
use lots of references and only references from pictures (using other peoples' drawings can exaggerate mistakes)
hope this wasnt too long, and that it helped, and good luck ^_^ youre doing good so far~
