Huh, feels kind of odd to see you here, but I guess it was inevitable after scrolling through so much. Anyways, don’t bother about the bitching on 4chan, though from what I’ve seen, you haven’t. Everyone develops an art style differently. However, and I know you’ve been told this so many times, but using less guidelines would actually make you improve a lot more. Don’t get me wrong, this system of repetition will work to help you improve, but only very slowly and even then, only very basic poses. Do me a favor, treat this like a request, you can ignore it if you’d like, but draw one of these poses https://s-media-cache-ak0.pinimg.com/originals/52/a9/ba/52a9ba2371ca0860565ad778e81fecb8.jpg in your own style. You can post it if you’d like, I’d be very excited to see what you can do with one of those!

They asked you to draw a different pose, so you just drew her at a slightly different angle.  
This is why they bitch at you.
