Here's my latest attempt, I am now using a dusk HDR, purchased from cg source as suggested but i'm still not happy with the result. I'm using only skylight in the daylight system which is using the environment to light. The HDR is loaded into the environment.
Also I still can't get the glass reflections working very well, i've tried using a fall off map but it seems to make the glass look a bit 'frosty' at certain angles. Would anyone have any suggestions or links to a good glass tutorial I could use? Any other comments welcome...
