I like it. I don't know if you're a big fan of charcoal, but I usually just take charcoal to do the backgrounds. I think a black background for this would be powerful. What I do is I use a black gel pen (for the fine details) that dries quickly. Then I shade over it in charcoal.
Thats smart. I've never really tried charcoal. I usually draw in pen, because it gives more emphasis and doesn't smudge like pencils. Also, for me at least, it looks good even if its sloppy. What exactly do u like <.< ?
What do I like? I like to use "Weber: Finest Quality: ARTIST'S CHARCOAL: American Willow with pointer." These are the only kind of gel pens I use. [link]
I use cheap pens, like from the dollar store. I personally think their better for shading purposes. Gel pens, depending on the brand, usually bleed on me. Sometimes thats helpful, though.
You can buy them at normal grocery stores. It depends where you live, but they should have them at Albertson's, Safeway, Rosaures, Staples, or Office Depot.
The problem I find with normal pens or other gel pens aside from the bleeding is that they aren't fine enough to get very fine details. Like with small details.
If you get charcoal and what the picture to keep you have to spray it with a special chemical that can be a bit dangerous. I generally just take a picture of it and save that picture to my thumb drive.
