Hi OSTexo - it looks great!

I'd say the model itself looks really realistic - but maybe the environment a bit less so. Maybe the shadow underneath slightly too sharp and dark, and maybe some more variation in the environment between walls and the floor? I know in a studio shot you don't want to attract attention to the environment but that's the only part that doesn't quite seem totally realistic there.

If you want to make a more realistic render, you will need to fillet or chamfer all the 90 degree edges that are visible. The renderer then will pick up highlights on the edges and it will improve the final product immensely.

When you produce drawings for production, the rounds and chamfers don't always have to be modelled as they are often implicit in the production process. When modelling for rendering, you will have to add them yourself.

I would choose a different viewing angle. Show the viewer some of the top and side of the unit for a better sense of perspective.

Other than that it's really nice for a studio shot.
