Thank you - for drawing I use Faber Castell Polychromos pencils, they are for graphic artists and you can use them over and with any medium (oils, watercolor, acrylics). My husband got me interested in them (he´s a traditional airbrusher). Apart from that just cardboard wipers to soften the lines and - of course :-) - an eraser for the highlights.

Thank you - I drew this on watercolor paper to achieve the effect, worked quite well :-)
