I recently finally made the plunge and bought a drawing tablet (Wacom Intuos Pen and Touch Small Tablet) and have been experimenting with it. Below are a couple more I did with my new tablet:

I've discovered that nothing beats putting pen to paper for drawing, but I'm enjoying using it for coloring and enhancing pictures. It takes some getting used to though. I've been using the tablet with Corel Painter Essentials. Corel Painter offers the closest real life experience for using various mediums. I would've gotten a better version of Corel Painter, but (I'm almost too embarrassed to say this) I discovered I have an outdated Windows platform (Vista!). I only really use my computer for internet stuff so I totally forgot what platform I had and now it's gotten to the point where I'll probably get a new one sometime soon so what's the point of updating it now. Anyways, long story short - I'm having fun with my new Wacom tablet with Corel Painter Essentials. I'll still do black & white as my main style (color takes a lot longer and I'm so impatient) but I'll be experimenting more with color.
