Well, what kind of stuff do you want to draw???
I got started into drawing with a book called "How to draw Comics the MARVEL Way" back in the early 80's.
When I switched over to digital, I dropped drawing all together and went 3D (modeling/shading/rendering) for many many years, that killed my drawing skill, lol.
In the last few years I got back into Digital 2D/Animation and picked up the old copy of HTDCTMW. I use both Vector and Raster tools, Vector for the Inking (sometimes Raster) and Raster for the Color (Dodge/Burn/Alpha Selections) Depending on the style needed for the project.
But its kinda hard to give advice if I don't know what kind of art you want to produce.
