I understand when somebody corrects something on a piece you did and you know very well they're wrong (i.e. "um boobs dont droop lol they go in2 a cleavage naturaly : PP"), but if somebody is genuinely giving tips like telling you how to shade or highlight properly or showing you some guides, please don't just go, "nah lol i like my style : P".
If you like your style and don't seek improvement, I have no idea why you're on DeviantArt. How about you send your kind critics over to me so I can actually improve since you apparently don't want to.
It's annoying, and we just want you to become better. Be a bit grateful that somebody tells you that just adding black doesn't mean the object is shaded and instead just looks like a terrible shading.
What's more, when critiquing, "wow this sucks...the proportions are so fuckin off:// stop drawin lol.." is not a critique. It's an insult and demeaning and does the exact opposite of what a critique should do; it discourages the practice of art.
Remember, if they don't tell you why it sucks, they're not a critic, they're an asshole.
