Tuba Okamenzu(Cockatiels)

This is an illustration of my participation in a late-night 2-hour DTM.
The subject was “a song using tuba”.
The illustration is of the cockatiels struggling to play the tuba.
The cockatiel say, “Oops! Isn’t it almost impossible to play this tuba?”
Suddenly they’re a very realistic size, aren’t they?
I have also uploaded a song inspired by this illustration on Twitter.
I made it in a jazz style using piano and tuba.
You can listen to it if you like 📯.
