Every 3D artist must continue developing his skills, otherwise, there will be a common situation: 3D artist writes in his portfolio that he has 10 years of experience, but his quality is below average.
That's why to sharpen our skills - we did this interior render, just to proof - we're not hit a plateau yet and there is always room for improvements in our skills...
Interior was done using photo-reference: the main idea - replicate the photo as much as possible.
Any criticism is always welcome...
