Nice one but for me the YouTube logo is bad. You should use the original one and add more material design to it. YouTube already has a material design redesign itself. You can get it here. It also works with every Google Product but after signing out it won’t work. See here: https://thechipped.website/use-more-material-design-d50493bba466#.2s7jb8775
I prepared that blog post on my Publication and you need to try doing that. That’s very cool for doing it. Try it!
