Thanks, everyone. Lot's of good advice. Getting smooth transitions on white highlights is going to be tough, so I'll have to rethink my approach a bit. I know a number of people have a lot of luck with oils on horses, I'm not sure I want to try it for the first time mid project. But it's definitely something I should start experimenting with.
I put the horse on hold this past weekend and picked up one of the Andrea Warlord Saga figures. Both the knight and the 90mm Roman are long term projects and I wanted something I could finish relatively quickly. That being said, the most interesting projects are the ones that challenge us therefore I'm jumping head first into OSL with Olfo, a lantern carrying hobbit. The limit of my experience with OSL is a vaguely glowing plasma pistol on a space marine, so I'm definitely pushing myself with this figure. I started him on Saturday and by Sunday evening I'd already stripped him and began again. He needs a little more work before I take any pictures, but hopefully I'll post some in a day or two. Assuming I don't screw him up too much (or get distracted by yet another project) I'll enter him in the contest over at the 5th Dimension blog.
