Maybe make the title like ones of these:
- From Sketch to Keychain (feat. @shirakamifubuki)
- Making a Cute Keychain (feat. @shirakamifubuki)
- How I Turned Shirakami Fubuki’s Sketch Into a Cute Keychain with 3D Printing
Something that has keywords to catch people searching for this kind of stuff such as fans of Fubuki, or 3d printing enthusiasts, or people who enjoy cute little sketches like this.
The thumbnail can be improved to include the original sketch on the left and your final outcome on the right, making them the only 2 things that appear on the thumb; along with a neutral/gradient background that lets the images pop
Apart from that I think it’s a good video initially. You show the final product right away which is a huge plus, good music choice, but your voice audio can be a little louder. That or just turn down your bg music a bit more when you’re talking
