Just on the velvia curve(

is it a custom/ proprietary
PS plugin/filter ?).
Well and truely oversaturated. Very unnatural, almost like a cross processing effect. To me, it looks like a very bad white balance .
For other subject matter it might be a creative effect - say fashion/art photos, but for architecture....? Not to my taste.
Oh and now that im here-
The converging verticals are a big no no - almost all decent architectural photogs use large format cameras with adjustable standards to compensate for this distortion. Very hard to fix with a 35mm.( i personally wouldnt waste my time doing architecture with a 35)
Compositions unbalanced as well. To many forground distractions leading the eye away from the main subject.
Just my opinion, mind you.
(Hopefully helpful )
