Finished picture under natural light. This was color pencils on proofgrade draftboard. It is currently getting some acrylic sealer to protect the pencil color, after which I will probably put one or two coats of clear spray paint for the gloss. Sadly, the sealer darkens the MDF a little, too.
For a video of the process showing more of the color steps:
Gorgeous! Here’s a tip for colored things like this: if you use Prismacolor pencils (which are a wax-based pencil) you can go over the solid colored parts with a paper stump dipped in odorless mineral spirits, and it will blend the color to give you a more solid look. Draftboard takes Prismacolor really well and I’ll bet Baltic birch does as well, although I haven’t tried it.
Lacking in prismacolor. Last time I looked at them, I couldn’t afford them. Another thing you can do, which I didn’t try on this one, is dipping the pencil tip in petroleum jelly prior to applying to paper/whatever. It has interesting effects.
