to be honest I don't like too much the first two renders (maybe because I'm usual to see more attractive view from you
...but i'ts just a personal opinion), they are certainly really good renders but I don't fell to be captured from them and quite immediately I'm in the need to see the next image.
Different opinion for thefourth and fifth image, they likes me a lot and I love how you're able to balance interior and exterior light (the background of the fifth image is a photo or a 3D environment?)
...all your exterior shots are simply amazing (the new one it's certainly one of my favorite...no bump for the concrete stairs?).
