Personal housing project. The main idea is to buil a house with sustainable elements aplied to general design,low energy consumption, recicled materials, etc.
Very good renders.
The drapery in the 3rd image is open in too wide of folds. Tighten them up, they look like they are made from a very stiff material, and they should look airy and light to soften the room.
The pillows in the 3rd shot are some of the best I have seen.
The 4th shot only looks "off" like davide P said, because your camera ratio is so wild. Trim off the top and a little of the bottom to bring the image into a 3:4 ratio to get rid of the distracting distortion.
Good job on the materials and lighting, they look very convincing.
