Lighting - First Attempt

I was playing around with my lights this morning and took these two shots. The subject is a Kodak Retina that a friend of my Dad's bought for him while in Germany, around 1944. It's sitting on a few pieces of white paper. I used 2 B800's, one with a 45" umbrella camera left, and one with a 30" umbrella 90 degrees to camera right. Both lights were about 6' from the subject.

#1 is ISO 100, 1/125 @ f/18
#2 is ISO 100, 1/80 @ f/13

I'm not sure if either of these are representative of "good" lighting or not, so opinions are appreciated. Personally, I think #2 is better, but I'm new to this. One thing I realized shooting at f/18 is that I have a very dirty CMOS sensor :eek:
