yeah sure. like anything you can find a bunch of tutorials on jewtube, and also I have a folder full of this kind of thing, which I got mostly from pinterest.

2 universal principles of art that apply to any art form:
1 - have a commitment to practice a certain amount every day. natural talent may give some people a head start, but practice is the sole arbiter of whether you'll develop a skill.
2 - start with an abstract concept and slowly get more specific. in the case of visual art this means start with a scribble in the general shape of what you're going for and then a slightly more accurate one, and slightly more, until you do the final layer. draw very light at first and slowly get darker.
