I decided to challenge myself a little this time by using more than one subject (that and I re-read Mark's tutorial and it said you really should have at least 3 items to get the most out of his teaching). Thank God I watched a video where Mark said stuff will look like crap but just hang in there until you get all the paint on the canvas, because when I was doing the goblet I felt the only way to save it was to burn the canvas.
Couple of things:
1. I'm toying with adding a red wine spill to round out the "drunken" nature of the painting.
2. The shadow below the tablecloth looks too dark to me, but I did check the value with my color checker and it seemed right (although it's possible I'm just inept).
In any event, I'd be grateful for suggestions to improve what I've done so far. For some reason I didn't shoot the photo from quite as high as I've been sitting while painting, so it looks a little different (mostly the shadows).
