A couple things...
1. I would suggest changing it from saying Spotify to maybe saying DJ mix. I was planning on doing themed ones. These (like on my mixcloud) take a few hours to make; from concept, to track selection, to track order, to mixing intros and outros... I have never used Spotify so i am not sure how it is. But, i suppose I can check it out, if it is the easiest thing for it. But, with the DJ mix I can sequence it and mix it in a narrative form (all of my mixes tell some kind of story, most can be figured out reading the song titles) and even burn it to a cd and mail it out.
2. You might want to change the amount of drawings from 10. It takes me anywhere from 10 hours to 20 to do a drawing. For example, the first one I had listed on that page, of the wrestler Y2J, took me about 12 hours to pencil and ink. I would say less (maybe 5 to 7) would be better...
