sounds just like me. taking a break from drawing because i don't have time to do art at moment being busy with work that has taken a lot of my time. The fractal program has been giving me ideas for future work
I use Prismacolor pencils, which I like for the soft, easy-to blend leads; though I have heard several other brands are excellent (Koh-i-noor, Faber-Castel and Lyra come up often). For skin tones I use a range of yellows, pinks, oranges and browns; Cream and Light Peach for the palest tones; Jasmine, Deco Pink, Blush Pink, Seashell Pink and Deco Orange for the light colours; Yellow Ochre, Mineral Orange, Goldenrod and Burnt Ochre for mid-tones; Pumpkin Orange, Terra Cotta, Dark Umber, Tuscan Red and Black for dark tones. Not all of them on every picture - it depends on the individual. And then whatever colour I use in the background, I add some of that in the reflective areas of the skin, to make the subject blend in to his or her environment.
I think Prismacolor has a skin tone set with most of these colours, but you can buy them individually at most art stores, as well.
