Well, I'm not planning on getting a tablet any time soon, but I'm sure there are still plenty of other options for digital drawing. I have a couple apps on my phone, but I don't think those are for 'top notch' drawings, just note taking, doodling and finger painting. I would think it'd be difficult to do a character sketch with one of the ones I've got. But there are plenty of others to try.
And yes, I do want to keep up with drawing, I have a list of books on drawing topics on my wish list. One of the books is how to draw wizards, witches and warlocks. Sounds like a fun book. I could definitely use a how-to on that.
