So. Many. Things. Wrong. With. This.
First of all, your grammar is atrocious. You went on anon because you were not trying to get blocked, do you perhaps mean you went on anon because you were trying not to get blocked?
Secondly, it's only helping IF the recipient specifically asked for help. Elfie didn't ask for any help. She posted her artwork to show a completed project and because she was proud/happy of what she had accomplished with it. The only acceptable courses of action presented to you were:
Admire it quietly, maybe like it or reblog it.
Admire it vocally and leave a comment or when reblogging say something or tag it.
Not enjoy the post and literally SAY NOTHING.
You ever hear the phrase "silence is golden"? You would have been rich had you kept your trap shut.
Thirdly, you're backpedaling now and trying to cover your ass because you got caught out. You're getting caught out again anon. She might not care but I sure as shit do.
Fourth, if you were just trying to "help" and it was genuine help, why would you need to hide behind anon? Why would any decent human being block another for helping them?
You knew damn well what you were doing. You knew you were not helping, that's why you hid your ass. You knew you were being critical and controlling, that's why you hid your username.
You hid like a coward and now we can add sniveling to that. Because you're still hiding behind anon as you try to weasel yourself to absolution. It won't work.
Finally, "just tryna help", oh really?
"hey not tryna be rude or nothin but I think your art would greatly improve if you studied some shading techniques or somethin. I’m really not tryna hate but from one artist to another, I just feel like your pieces would be more effective if the shading was more pronounced/dramatic ok bye"
Let's break that down shall we? I previously pointed out "not trying to hate but" = definitely hating & "not trying to be rude but" = definitely meant to be rude.
"I think..." You came at her with your personal thoughts, which she never asked for. Right off the bat you're proving you're not helping because your thoughts are not facts, they're just your thoughts and in this case nothing more than your personal opinion which is again, not a fact.
You think her art would improve greatly if she studied x, y, or z. Again, personal opinion. You claim to be an artist as well and yet you cannot seem to pinpoint what it is about Elfie's art that you think is holding her back. Shading techniques or something. Your literal words.
The "or something" implies that you don't really know what it is about her art you want her to fix OR you know exactly what you want her to fix for you but you were at least smart enough to not say it out loud. And you never will now because you know I'll have some choice words for you.
"I just feel like your pieces..." None of this is help, all of this is your personal opinion which we can clearly see is a negative opinion for whatever reason. You don't like Elfie's art but rather than be quiet about it and simply not consume her art, you decided you could hide in the shadows and try to tear her down.
She's been making art for a long time and she knows her skill and her worth. She's not weak nor is she soft. She has a confidence in herself, her craft, her skill with said craft, and her pieces. You won't tear her down like you thought but you will piss off her friend, which you have done TWICE.
And on the exponentially dwindling off chance that you were indeed trying to offer some insight, you seriously lack communication skills. Your tone is offensive, your word choice is negative, and your delivery is hurtful.
I suggest reading some books on communication putting an emphasis on written communication. And buy yourself a decent grammar book and a dictionary.
Next time you want to offer unsolicited help/advice, do so with your username so people can see your art as demonstration of said techniques. Work on communication, otherwise:
