The Metro stations have enclosed platforms and the rail line is elevated - limiting the viewing of images.. Many buildings, especially on the East side of Sheik Zayed Road would benefit from seeing the colourful artwork passing their windows.  However buildings and pedestrians on the west side could also benefit if the graphics were strong enough.  They need to work when viewed accross 14 lanes of highway.  The reference picture here was takeb from ta first floor balcony opposite JLT.
