Hello,
I was able to see a translation of the website, but I had to manually request a translation. Not every browser allows that, as Chrome does. Naturally, when it is translated, you cannot be sure that everything is done well. It would be beneficial to create an English version so that the translation is done accurately. You can have it set to change automatically or be able to switch between languages at the top of the screen. This will also reduce loading time when translating, as you will already have everything done.
Visually, you have selected excellent renderings, but you should limit the number of images in the slideshow. Since you can scroll down and see the grid of images, the slideshow does not need so many. Try selecting one image from different types of projects (i.e. one bedroom, one residential exterior, one city aerial, etc.). Additionally, try providing names to your images. As I see it, they are just numbered when viewing the images on the home page in a lightbox. If I was looking to reach out to you for work, I would like to reference images on your website by name rather than saying "Image number 20 is a great living room."
On the subpages, things start to look strange. It could be part of the translation process, but the text becomes right justified, periods are randomly placed, and the font color changes; all which dissuades people from wanting to read more. (See the image I have attached.)
You have all the necessary components on the website for explaining your process and showing off your work, but it comes down to making it visually appealing.
