2nd view is very flat, maybe due to the use of tele lens. the repetition is a bit too much I guess, if this is for marketing, it only shows that there's too many typicals in the development.
- Overal the render looks too washed, try a backlit lighting so your walls be in the shadow, it might soften the appearance
- Be careful in placing your people, their scale are off, make sure the closer they are to camera, the bigger they become. Some distant people looks a lot bigger. Also the scale of the people in right hand foreground are too much different from the rest. I can't tell which are correct.
Try render simple a dummy box / square at the size of 600mm x 600mm x 1800mm (h) for height check, scatter them around so you don't lose track of scale.
3rd view is the same as 2nd. I don't really know what this image conveys as it is more of a 'checking the design' view. You need to try a bit more creative angle, use wider lens, go inside the balcony and try some shots, just as you are with actual camera, you will try to move around and take lots of snapshots. A good angle will make the image half finished already, so you might need to pay special attention to that. It might take the attention away from unfinished details. Bad / uninteresting angle makes the eye wander to find other things that a bit 'off'
Just my opinion
