Thumbnail Feedback is the style good?

I really am trying!!!

I think those thumbnails look really good! The only thing I would suggest is to add some additional text onto the thumbnails. I wouldn't be able to tell what your videos are about just as first glance of the thumbnail.

The style should be about what you like and what you're building for your channel. You don't have to have the same style as similar creators.
