I've been thinking of this question for some time! Generally speaking, there's a lot of great artists out there, but the ones I adore the most are Dolman and Yongje Park.
https://www.instagram.com/dolman_00/?hl=en - I've seen his works on Pinterest. Everything about his art style speaks fun, vibrant, and colorful to me. It gets my creative juices flowing and that's what I like.
Next is Yongje Park, famously known as the creator of God of Highschool. His fictional work originated from Webtoon before the series got produced into an anime. The Webtoon version has more of a classy, action-themed atmosphere to it. Don't know why, but I love the idea of tinted (or rosy) facial features like at the brim of a nose or the ears xD
