Hi! Looks like you have a nice area! Here are a few suggestions :
Have you considered chairs with color to bring out that great Chicago art work?

These are a little more subtle and classic:

What kind of light are you thinking of? There are so, so many different styles--do you want something like the chandelier you already have or something that's kind of a linear kitchen-island style fixture? Also, do you have any preferences for style (modern, traditional, etc.) or finish (bronze, nickel, etc.)? Let's narrow it down a bit.

i was considering a drum style but not sure and i think it needs to be oval or rectangle? not as traditional as what i have now. trim should be stainless / brushed to match other metal accents. thanks!

Excellent! Now here are a few possible choices. These are drums with metallic finishes.

These are kitchen island lights, meaning they're a bit more linear.
