I am a casual Anime watcher and a Manga reader. Some people might find my anime rating system to be kinda weird as I don't give high ratings to a show just because I personally like it. I try to keep a line between personally admiring a story and judging the work itself.
In case of animators, I prefer The AMaaZing, Emirichu,Eroldstory,Daidus, The Odd1s out, It's Alex Clark and Domics.
In case of cover artists,I prefer Nathan Sharp from Natewantstobattle.
