I've looked through your art,and It's pretty cool.It's nice to see the excitement you have with your art.
Buuut,there are some points here and there I notice and like to share for all I can.
First one Is that I think you should take It a bit slower.Take your time In between of making actual pieces and use the time to study and practice,because that's really Important.Else,you'll Improve too slow for your own good.That's why you shouldn't get on with webcomics that quick after starting to make art,because If you're pretty tight on your schedule In general,and you are pretty punctual on when you release new chapters/pages (which Is a very nice thing If you're like that,people really appreciate that),you'll pretty much won't have time left to study and practice,both theory and just practicing things to Improve on.
Second off,I think you should check your proportions more.You seem to get the basic of some anatomy,which Is good.But the proportions look kind of weird.I see a lot of characters having very short legs and arms and sometimes It completely contradicts with the overall weight some of them seem to have.
Third,and last,I really recommend to practice just THAT what you dislike,or hate,or have trouble with.Mastering styles and aspects that you really would rather throw away In the bin can make you even better at what you're doing sometimes.
Fuck,I really have to compliment you on your coloring and background though.Especially this Is amazing :

the problem Is,If you get ahead of yourself with art while you seem to lack some basics,most times,It really goes the wrong way and It's really hard to get back at learning from the start.But you seem to be doing pretty fine with that,which I'm glad about.
Again,I really recommend just taking your time and do some studying.But most Importantly,to enjoy It and you seem to be having a good time,which makes me glad.Do your best!
