5 - I like the perspective, the water element and of course the train - which is easy to miss on first go - (no pun intended) - but at this size, wonder whether the OOF fore dominates a little too much. The border, also at this size, especially the grey in it, is detracting - in my opinion.
Would I hang this on my wall. Probably not, but still an interesting picture. However I judge on what I would hang in my apartment. I am not sure if I would classify this as "fine art". Nevertheless a good pic. for an other competition. At the moment you will have to live with my 4.
