Music Buddies

Lately, I found myself drawing a ton of anthropomorphic characters. What I do is look around Pinterest to find some cute / Silly/funny / Stylish animals, collect a group or just one, and draw them, mostly groups to get interactions.

These were all 4 random animals, most of them were just as a burst, ex. The cool orange cat, it was only a burst, so I had to add the rest.
But the chihuahua started this picture, I knew I wanted to draw a setting, the picture had this dog lying down with the music and a blue hat, so I took it from there on and added on.

I imagine it's 4 friends hanging out in the basement room of the chihuahua, listening to some sweet tracks, this would be around the 60s I think.
