Thought this looked familiar, and then I saw that you are in Portland - is this North Pearl? Like the technique, but the composition and lighting especially need some work. Of the two, I like the warmer tones of the second image.
With camera placement I try to avoid a 45-degree angle (in plan) when looking at the building corner, it's almost always better to emphasize one elevation over the other. And the light levels on the left & right sides are too similar, and so there is not emphasis there either. The lighting in the MAX render favors the right elevation, but in PS you've dulled down the shadowing too much and lost the "punch". If you can get away with it, it might be worth omitting the large building off-camera to the right so that the entrance / streetscape are not in shadow. You could also look at a steeper sun angle (not recommended but could work) or bring the sun around to the right or left, whichever way works to get sunlight on the building entrance.
Don't know if the taller adjacent building is part of the project or not - if not you may want to back off on some of its detail, if it is then it seems like we should see the whole thing and punch up the lighting on the short building to maintain its focus. Back to composition, what is the focus of the rendering? This camera position does a good job of explaining the architectural massing, etc. of the building, but not what it feels like to be there. Perhaps you could look at a street-level viewpoint that would emphasize the building approach from a more natural point of view. It's a tight space to be sure, you may have to omit some of the neighboring buildings to get a viewpoint that is flattering to the overall project.
There is a lot of detail in the background building at the right edge of the frame, but the buildings to the left are just white boxes - it would help if both sides had a more similar treatment.
Definitely lose the foreground box at the lower right (if you can) and lighten up the forecourt at the right center of the image. Seems like this street is a big amenity for the project and should be showcased accordingly.
Greens & blues are very desaturated in the warm scheme, and cyan is too dominant in the cool scheme. Try to develop a color contrast within the image to get a good balance of cool and warm colors. The trees left and right would be a good opportunity to bring in some more color.
I hope this is helpful to you, I really like the project and this is certainly a good start!
