Before I say anything else, I'm just going to tell you that my art style is very unrealistic, it's sort of of cartoony or anime-ish. I also cannot draw muscular or old people. To give you an idea of what my art looks like and what I can draw, I'm going to link a picture of a drawing from one of my biggest inspirations: https://pbs.twimg.com/media/E0Q6SJ5VgAI0z1O.jpg (art credit: lovoviii on twitter)
Note that my art doesn't look like this, it's just one of my biggest inspirations. This is just what most of my characters generally look like in terms of age, and my style is kind of cartoony and unrealistic like that. I'm also better at drawing girl anatomy than boy anatomy, but I can still try.
Now that that's out of the way, if you want me to draw your character, just link a picrew, post a description, or just anything that will help me understand how I should draw them! You can also request me to draw a character that isn't yours, such as a character from a show. My drawings are all done on paper, usually with a regular pencil (sometimes pen.) Again I'm doing this for fun so please don't expect anything great from me. I might not do all of them, but the ones I do end up doing will be finished by Monday. (I have things to do this weekend lol.)
