You are definitely getting the hang of composing with an uber-wide lens, KUDO's! Just so folks are aware, the 23 on FF MF is roughly equivalent to a 15mm rectilinear projection on 35mm DSLR. However, with MF, at least to my eyes, that extreme wide projection is more believable than it is from a DSLR. Anyway, impressive work Charles, especially considering you only had the lens for a day when these were taken!
