The first attempts to render. What else to work on?
Nice job!
Now try to play with lighting.. there's a great Keyshot webinar on how to tackle interior lighting with area / IES lights.

Nice start! Good test bed for physical lights, like IES, which would really help kick it for you.
Also, you may want to move the chair on the left a bit, and maybe rotate it. As is, it demonstrates
"tangency", an issue we all deal with. Notice how the top of the chair is perfectly lined up to the arm of the sofa- this is tangency. Just a little shift of position, and perhaps rotation, will separate the chair from the sofa.
Keep us posted!
