I am not sure if the softness and relatively overcast look is deliberate. Although there are blue skies in the third shot. Aside from the lighting I found the few photos quite good. Personally, the BW could use atad more contrast.
I also used the Minolta S404 and loved it even with its quirks. It had the right heft and the glass lens was exceptional for the price. If you have time you can view some my S404 shots athttp://www.pbase.com/selvin Aloha
