My first tshirt design

Been going through some of my old clothes from back when I was a child, and came across this.
My first tshirt design :) Hand drawn with some sort of textile crayons on a black tshirt.

The front features a rainbow, some sort of santa clause looking guy down in the left corner, a house in the lower right corner and the text "Kenny 4 år" which translates to "Kenny 4 years" I guess that means I was 4 when I made it :)
The back has some sort of gangsta motif, haha a Gun and the words "pi pii pii", I have no idea what that was all about.
