(*cough* longish response i almost started makin a lil rant on dahub watches and jngsgdfs unimportant crap .3. *cough*)well for the drawing part; lots of practice and staring at references, even if you only look at them once it helps drastically sometimes
but after a while you will indeed get better, also always accept critism, or at least keep the critism in mind when drawing ^U^
as for the watcher part...well...
you really shouldn't be taking advice from someone who took 3 years to get in the 80's for their watchers but- for starters, befriend some people, support each other, also be nice to others obviously, perhaps find people who'll give you a shoutout (although i wouldn't go around going "yo gimme a shoutout please" all the time) and try getting fans from your youtube/tumblr/whateve to come onto DA and watch you, it's really slow at first but things will pick up over time
then there's dahub, if you pay them enough points, you get to be featured in the area where people will watch you to get points of their own for a certain amount of time, i don't recommend this as it means they'll probably unwatch or not be an active watcher after getting points
also tip: when you start getting a hater or 2, take it as a compliment, cause they're spending so much time thinking about you ow< hold up i tink i know you :0c
