>>2093355I'm by no means a good drawer, but I do have a wacom tablet as well, and I've done some tracing and sketching by reference. I used the program that comes with the installation disc of the tablet, SketchBook Express. It allows for varying weights on the pen for darker/lighter lines, so it feels a lot like sketching on real paper. I don't know what other programs have that, but I haven't any qualms with SketchBook, so I continue to use it. It also has layers that you can change the opacity of, similar to Photoshop and Illustrator and such.
As far as actually drawing, I can't help you, but hopefully someone else will have some good advice.
