Eye catching thumbnails/ channel art?

I agree in everything. I don't feel atract to videos with very colorful thumbnails, or with a lot of information on them. I prefer simple.
Great example with pewdiepie's thumbnails. Love him or hate him you got to admit he has some attention grabbing thumbnails.
if you guys would like to know how to make cool thumbnails and channel art, let me know on my channel and i am happy to make a video about whatever you guys have requested!
