Take a look at the comparisons i made for you between the 3 x 2 ( 16 x 24) ratio of my original picture and what a 4 x 5 ( 16 x 20 ) ratio looks like - just to make sure you are ok with the crop. All the originals are the top photos. Don't mind the editing quality of the last picture of church st in snow, it's old.

Pricing for prints
I really like maintaining the original ratios but as you can see none of the images truly lose their dimension except for the greenhouse a little bit. I would recommend printing a 16 x 24 of that. There will be two prices offered for you as well - the Price of a standard quality art print and the price of an archival museum quality print.
16 x 20 - $60 / $100
16 x 24 - $70 / $110
12 x 18 - $55 / $95
10 x 20 - $55 / $95
all prices exclude $20 for shipping ($20 whether you order 1 print or 100 prints)
I offered the 10 x 20 size if you would like the original 2 x 1 ratio of the church st snow scene. Otherwise I recommend a 16 x 24. I was a little confused about the request for the church st snow scene sizing - you had said 2 x 3 or 2 x 4 was fine, is that the size you are looking for, or just the ratio?
