I’ve been given permission to post this here. I’d really like some feedback on what you guys think. At first glance to me it looks pretty cool, but theres something not quite right about the lighting. It doesn’t look like a warm sunny day - it’s like you’re looking through tinted glass or something. I’ve been working on it too long to be able to pick up quite what’s wrong with it! Any suggestions are welcome 
Maybe add a little more contrast in your shadow, it is looking a little flat. Also the camera angle and vertical shift has made it look flat. Maybe try a new angle?
You could also try adjusting the white balance on your vray camera (if you are using one), use a daylight colour… 191, 226, 255, might help add some warmth to the image.
The detail looks great!!
just give it a “yellow tint” in post. Agree with TimmeH, the angle looks strange and its stretching the building too much
I can’t see much wrong with the white balance, but some shift towards red/yellow could help. Leaves of the trees could be lighter and more yellowish in my opinion. Maybe some light cirrus skies would add to the summer feeling… Otherwise great modelling!
