At the moment with some feedback from other people I think the composition could be improved by moving the painting 20cm to the left and sofa with all the stuff on the floor 5 or 10 cm to the right, there is an area of complete blackness under the sofa, that is too much so I should put some light there and maybe make the base of the sofa a bit lighter, so there is detail there. There is also this weird white blob on the pillow under where the floor lamp is pointed at. I also now think that the fabric of the sofa is not exactly the best I can do so I think it needs to be redone completely. I should also use a proper canvas texture on the bump of the painting instead of the terrible noise there that I am ashamed of now. I am thinking maybe I could put a knit blanket on the sofa as well. That would make the scene too full, kind of overcrowded even more with the painting and the ceiling lamp already competing for attention too much, but it could also add more detail and realism and would be a great way to show off my technical skills, as I might decide to use this in my portfolio maybe. Would be nice to hear some feedback on that.
Should I be thinking of improving anything else?
