This is a recent personal illustration to try out some pens I got from the kind folks over at JetPens.com. The majority of the black linework, and some fills, was done with a Copic Multiliner. This guy works how it should like any good tool. My only problem with it is the ridge on the barrel that meets the bottom of the cap is right under my fingers most of the time, which becomes uncomfortable after awhile. Maybe I hold pens weird, but it seems like they should back it up a bit. All the red in the drawing was done with a Mitsubishi PIN (I didn't know Mitsubishi made pens either). I love this thing! Really comfortable to use, and great for accent colors like this piece. The character's flannel shirt is a technique that usually comes with a fair share of trial and error. In most cases I would fill in the whole shape black, and then come back in with white acrylic paint and a brush. But I prefer pens for this type of work on paper so I'm always looking for a good opaque white pen. JetPens sent me a Uni-Ball Signo Gel Pen, and I'm pretty happy with it. It's the most opaque I've found. You just have to be careful that the black ink is completely dry before you go over it. My only problem with the pen is that it leaves a fairly wide bead of ink, making it useless for fine detail.
The first image is an attempt to show the drawing quality. The other two are final vectorized versions, which I did because I might screenprint this.
