Wheel Shot

Ok at the moment i am really not happy with this shot it doesnt fit with the rest of the shots in terms of lighting and colour and how clean it is. The first image was my initial test the occlusion looks bad, its way to dark and dull, its boring.

My second attempt is from today, which i feel is better, but i still feel it is rather dull, the metal need to be more shiny on the bed, the dirty yellow needs to be lighter and have a more plastic feel. I am happy with the rubber wheel. Im not to sure on the bump on the bed. The cabinet just is a massive bit of colour in the background and the tiles and floor is to dull, but the shot is under the bed how bright is it realisticly going to be? If you guys feel the same as me and have any suggestions let me know! I also prefer the shadows from the old one, maybe an inbetween of the twos shadows?
