Drawing/Digital Painting classes for Bitcoin

[lumos]

hey, i am offering drawing/digital painting classes for bitcoin, these will be 15 bitcoin per hour, or 25 bitcoin for 2 hours(but you don't have to have it all at once). software used will be gimp with a plugin, or iscribble, or anything else with collaborative draw features if you have a better suggestion. these are 1 on 1 and can focus on any kind of art style/or things.
this is what i have been working on so far,
