Oh wow I love this a lot. Funnily enough I was thinking about getting the equipment and trying a bob ross painting the past month. I've never tried one and my lego order has been so long I lost the MOC spark I had going on.
I think it's pretty cool that you could "wing" details of this so that everyone's picture comes out slightly different. Either way this has been a sign for me to buy paint
