hey you're gestures are coming out very very well. In terms of progressing as an artist, really the only option is to keep pushing forward. I fully understand getting down, and feeling like people are piling on, but this, art that is, is something that when it really comes down to it; you're doing it for yourself. Don't worry about what your parents think, what anonymous people on the internet think, if criticism on your work is offered and you find it useful, great! If you thinks it's utter bullshit, just forget about it, move on. Getting bogged down in what someone else thinks about you and your work, just wastes time, valuable time you could be using to draw. Uhm really I don't know where I'm going with this...sorry it's pretty much me rambling, but good luck man...keep pushing yo have drawing skills and I'm sure you'll find your way to where you want to be soon enough. Good luck.
