With regard to your "inspiration" what i see is a dull, overcast misty day that gives the impression it either is, or has been raining, hence the reflections from the road surface. I did try to recreate the fountain by creating rooms a similar shape, changed the transparency, result was really poor, copied newmtl Layer_1_Extrusion_Material, came out pink, copied newmtl Layer_1_Back_Inflation_Material, no transparency, added hanging light to file, exported it, looked at mtl and copied section for glass shade, and rendered like a dark pineapple frond, so i thought, its late, i've been up since 4 i'll give up.

Outside moods of doom is a lamp post that is perfect for me to lean on, have a cigarette, while i wait for Deb to shop [;)].
Keep posting, i learn more every time i study your images.
