Mono-Wheel Under Painting for Oils

I'm doing an oil painting of the mono-wheel design.  I took a smaller sketch, grided it up and transfered that onto a board.  It's about 11x14.  I'm going to try and pull off my best "Ashley Wood" style.  Looking for rough and gritty.  I haven't done oils in maybe a year, so it'll be interesting.  Wish me luck :)
