You stole your thumbnail from MattShea... not cool man.
I didn't "Steal" anything from anyone. I found it on Google images and liked it. I have changed it tho if this was made by someone else.
Google Images isn't a collection of free images for you to use however you like, it's website that indexes image links from the web. It's your responsibility to find the source of the image and confirm if it belongs to someone, tip: 99% of the time it does. Make your own thumbnails. Channels get shut down daily due to copyright claims on thumbnail artwork, don't be one of those channels.
