Let's Dance for an Hour

I felt like drawing an unindentifiable animal with headphones.
I love headphones.
I drew that in about an hour and I'm pretty proud of it. I didn't really put a lot of effort, the lineart is weird and not very clean and that left front leg look weird. Ah well, I didn't feel like fixing it.
Let's say that green thing on the floor is a soundwave or something.
Also, someone got a trick with canva size? Do you have a trick to choose the right size or you just write whatever?
