Egg tempera allows for a lot of detail, and is appealing because it is extremely durable and long-lasting. One of my favourite pieces in the Musée des Beaux Arts here in Montreal is an egg tempera painting from 1410. It's a religious scene, but the red pigments in the skin have all faded, leaving only the greenish-grey underpainting. Everyone in the painting looks like a creepy space alien. The "space-alien effect" can be avoided in your own pieces by using stable pigments that won't fade over time.
"Dirt City" (above) is a personal coat of arms, a call-out to my home province with an oil-gushing sick heart over a yellow prairie, gorgeous sun and huge sky, and the Edmonton skyline in the distance. Realistically, you can't get a view like that of the city; from that distance, you would likely be standing in a suburban cul-de-sac (Edmonton has one of the lowest population densities of any city in the world, and in size is larger than Toronto).
"Noxema Girls Get Noticed" started out as a tribute to Yayoi Kusama, and ended...well, it's not quite done yet. I got off track and started thinking about the gender relations in the oil boom towns, and the syphilis outbreak in Fort McMurray and Northern Alberta. I'll re-post this when it's finished.
I'm planning on doing more with this medium because it's so wonderfully portable and easy to use. Eggs + pigment, and water to clean everything up. Easy. The fact that it dries almost instantly also makes it a nice change from those pesky oils. Though egg tempera (along with watercolour) has a bad rap because of it's association with cheesy subject matter, I think it has a lot of potential to liven up contemporary subject matter. At any rate, definitely worth continuing on with.
