I'm not just trolling you bro, but you have made no gains in 4 years. In a recent picture you posted of a zombie head, it looks like, ... i mean... if you posted that in beg i would tell you to look into loomis. the eyes are out of perspective and look flat. you didn't flip the canvas, you didn't draw a box, you haven't mastered the loomis head.
I mean if you just want to draw for fun, fine but I don't see why you think anyone would want your critique when you don't seem to accept the critique of others. When I see your drawings, it makes me want to avoid your advice because I don't want to end up like you.
I think you should really get serious about this. Take a legit class with a real teacher. What you've been doing isn't working.
You're not bad. I'm not saying that but you haven't improved whatsoever in 4 years. You could have graduated from art school by now. Instead you drew 1200 pointless mediocre sketches.
If what you are doing isn't working you have to change your method. Good luck.
