I think once you get rid of the vertical blinds (which look dated) and definitely upgrade that chandelier, there will be a huge difference. Doing the floors and trim will enhance the fresh look as well. I wouldn't give up on the paint yet - I think it will come a long ways when you're done. I think part of what you're missing right now is depth and texture, and those upgraded elements will help. How about some contemporary patterned drapes instead of white slatted blinds?

I also think right now the space is lacking a focal point - at least from what I can tell in the photos. This is the first chandelier that comes to my mind for your, and also hang it lower so it's closer above the table instead of up in the sky. :)
