After searching through DeviantArt, I narrowed it down to these 3 artists, because I thought they each had a distinctive style:
1) Bobsmade:
They create custom shoes and headphones for people, as well as some paintings and shirts.
Check out their website.
2) Jerrod Maruyama:
This person does a lot of character creation and illustration, and I think they used to work for Disney for designing products. Check out his website!
3) Skottie Young:
I learned about this person because of their Wizard of Oz series, and then one time I saw their printed comic in a comic store, so I became very interested. I found their blog too.
I’m still not 100% sure on which artist to study, but I’m leaning towards Skottie Young because their style is so dramatically different than the style I’m comfortable with.
