Today's concept paint theme is Caravans. More in the fantasy zone than sci-fi here, it looks like, but those worlds aren't that far apart. All of these 4-ups take about 1.5 to 2 hours; I'm not particularly hurrying on them, just trying to keep a pace of one set per day. Each one is a single PSD, with the black crossbars on their own layer. Everything else is painted either right on the background layer or done on one layer above that and quickly flattened.
Below, made a little more progress on the hovercraft last night, but didn't have a lot of time to put in. Still going well though, I think the hard work is all done.
Tired today. Gotta try to get to sleep earlier tonight. See you tomorrow!
