Roaring 20's Scratchboard - Finished

Ok, here is the Car Grille scratchboard completed.  Again was a very unusual subject for me, but I was attracted to the sky reflections on the black paint and the way the lights played over the chrome areas.  I enjoyed the process.  Not knowing a car intimately I was able to focus more on just shapes and hope it came together. 
I definitely am going to continue to pursue these scratchboards and am thinking about using multiple boards to complete a picture - have to think a bit more about that but kind of like that idea.  This will sit on the board now for a few days - I haven't sprayed/sealed any of my scratches yet, but have gotten some floater frames so think I'll put them up and hang them in a place I can continue to live with them for a while.  Hilda, these floater frames don't have glass.  Jury is out with scratch experts on whether to frame with or without glass.  I am going to see if I can get a scratch juried into a show in July - fingers crossed.
Painting tips:
1)  Don't outline subjects, rather let the dark colors create the edges for light areas. 
2)  Make sure brush strokes always follow the contours of the surface you are painting.
3)  Use contrast for more impact - don't be afraid to use lots of contrast in your paintings.
