#1. I really like this one - composition - leading lines, etc. Irrigation country in winter, with a nice fade into the foothills and mountains.
#2. Not sure what the subject is here - church, cross?? Image is nice and sharp, but is still just a snapshot.
I am curious about your B&W conversions as I am very interested in this type of work as well. How did you do them and did you do any processing before and/or after the conversion?
#2 is basically a good composition, but the cross should not be right at the frame edge. Either crop in some more on both sides and the top to emphasize the cross, shadow and steps, which are the key elements, or leave more room on both sides. It also appears to be lacking anything close to white. Even if there are a few tiny spots which are close to white, the highlights in general need a boost (boost curve at about 200?).
