I decided to practise tone again in this exercise as well as think about the perspective. on the tone front maybe I should have been bolder with the darker areas and added more mid tone to really make the highlights stand out. I think I can see a number of tonal values in there. The quest for depicting form continues..
Looking at linear perspective I can see some of the lines I made with out ruler where correct to the eye level and others such as the rug and right had mid wall are wrong. I found the eye level by measuring myself against the real door and marking the eye level with tape. I then put the horizon line on my drawing at the corresponding height. I measured to find the middle of the horizontal line then made parallel lines from that point.
