a classic tutorial. a few tips though - the handle on the cup is slightly off, when you extruded the handle on the top, you left a sharp edge. to fix this, you can move the vertices loop you made with CTRL + R before and then drag it away from the edge. This will make it smoother. Other than that great job.

It's pretty good, but a few things I'd working your lighting is a bit uneven, it appears as if you're only using only a single area light, thats works well enough but half the battle of any good render is lighting, I'd take a look at a few lighting tutorials to get your feet wet.
Also I'd add just slight bevel on the table, perfectly square coners don't exist in real life so add a slight bevel to a hard surface can make all the difference when trying to achieve a bit of realism.

Keep on practicing and nicely done.
