I was trying to help you out. I know you want to drop out of the game, that feeling happens to most beginners, but it's hard to know what you're missing out on.
Any skill takes a lot of work to make it worth it. The better art communities (other skills too) hanging out there tell it like it is, this critique sounds rough but you have to understand it's all earnest, or at least for my part it was.
I am no master myself but far along enough to tell you if you stick with it, it pays off. Pretty sure a lot of those other artists and everyone dishing out the good critique know this too.
I'm not tearing you down, just your art, and it gets stronger as a result. By all means keep at it
