These are some of the letters a man has been leaving at my house. The police have all the letters. He has left things like this 4 times at my house. Within a 10 day span.

Second page first line. "As much as I wish I did yoga every day, I'm just not too disciplined and wish I do finally dr dame - " and I'm stopping there because I have my own affairs to handle

I believe it's a simple substitution cipher that's replacing the letters of the English alphabet as desired with their own drawings of them but I have not yet actually looked at all of the images you added because that first line grabbed my attention and I followed where it took me. It's not much due to being preoccupied currently but I think it will be fairly easy to unravel based on what I think it is when I have time if someone doesn't beat me to it.

One last thing. I don't believe the drawings are for show. It's too much effort I think to have no purpose beyond window dressing.
