/ic/ - Artwork/Critique

I have no idea how to fix my lines. I want them to look more, idk, dynamic and less uniform. It's impossible for me to explain what I actually want, but I think you might be able to see what I mean through my work. I usually make lots of little marks to get them, because g-pen is too thick and hard. Means my final product looks something like this. I can't even copy correctly because I don't know the right brush to use for it. I'll post something else to illustrate even further after cooldown.
