In the meantime I've been "warming up" (by which I mean "dicking around") with sketches. There's a Twitter group called Sketch Dailies with posts a daily sketch topic and people draw it and it's a fun way to spend an hour or two when one is tired of work-drawing. Here's some of the sketches and topics I've done in the last month or two, in no particular order:
Troll:
The Invisible Man:
The Loch Ness Monster:
Favourite Muppet (the Swedish Chef):
Modern Samurai:
The Cookie Monster:
Unicorn:
Anyway. These short little activities help keep me creative and don't take up much time. They're a great thing to get into if one is suffering from any sort of creative "block". Just be careful about getting too wrapped up in the popularity contest aspect, nothing hurts creativity quite so much like feeling underappreciated.
Next time, Sketchcrawl sketches and then hopefully I'll have paintings to show off.
