The original perspective shot of the image alone is very good, but the "box-in-bevel" in my opinion...just doesn't look right. Isolating the cable car and keeping it color and making the rest of the image greyscale (or vice versa) would've been a better way of making things stand out...

Het is net of je de Cable car in een spiegel hebt gezet. Maar dat klopt niet. Wat je nu ziet is gezicht bedrog. Net als alle werken van Esher.

It is exactly or you the Cable car in a mirror have put. But that is
not correct. What you now see face fraud is. Just like all work of
Esher.

I like the fact that it shows so much of a real life street in San Fransisco, a very realistic photo of a beautiful city and the "box" in my opinion manages to highlight the cable car in an original way while on the same time adds a 3d sort of feeling. I really like your approach with this and think it's a lovely image.
