I got a wild hair recently to see if I could play with the logos/badges of various auto manufacturers and their products and drop a little impressionism/expressionism on them. It might make an interesting pop art series. Since I also recently bought a Cadillac (a VERY good deal on a used SRX that I couldn't pass up), I thought their latest logo crest would be a good place to start.
I found some Winsor & Newton Pigment Markers on clearance locally so I thought I'd give them a try. I just bought a couple grays as I've been wanting to experiment more with grayscale and with markers. This is a first attempt. Not bad if I say so myself. The two pens I chose were a bit darker than I expected. I was looking for four levels -- two grays, black and paper white. Not really what I got. Even so, they work nicely in a horror theme, obviously. I'll be playing with these some more for both finished pieces and preliminary grayscale sketches for watercolors.
