Your reference image has a piece of wood on the lower part, you've gone with glass. Not a bad choice however the assembly and mounting hardware used for glass is much different than the wood piece in the picture. If you want to get realism you'll want to add the details.
Example, what is holding the glass in place, how is it doing so? What are the parts involved made out of, and how big must they be to support it?
You seem to be off to a good start.
One other thing I might like to suggest is beveling or softening the edges. Even a wood table like that has softer edges than you might think. In Maya a box essentially has edges as sharp as a knife, for the exceptions of knives, there aren't many other things in the word as sharp and hard edged. Toss a small bevel on the edges, it will pay dividends in the renders too as the new faces will disperse light better.
