Having a challenge picking thumbnails for our videos. Do colorful backgrounds work better than a park scene? Our videos are mostly outdoors of my kids with toys. I know they're important so what do you think of my current thumbnails that I can improve, lighting/color etc? Also, any suggestions on the easiest way to pick thumbnails? Thx!

The kids market is all about the bright colors- park colours can be fine as long as they are bright! The images you have at the moment the lighting is great there is no changes needed :)

Your thumbnails seem very interesting and draw me in, maybe change the font a bit as it was a little hard to read straight away, make it really bold and clear!
