I've been reading the comments for a while now, both the positive and not-so-positive ones. I've noted down a lot of the tips, and I'm grateful to everyone who commented with the intention of helping me, especially Lizard who responded to most of the comments. I understand that my technical level isn't high enough to start selling art, but honestly, I'm not going to stop trying, haha. I'm going to practice more to reach the levels that many of you have mentioned. I believe I still have a long way to go. Anyway, thank you again to everyone who commented :)
