agree with BE, it does look very "inviting" :-).  I think the wood is quite
dark, and a "sun-bleached" version would set off the drink better.

Jaime Vives Piqueres gave some beer coasters in (archived only):

This looks really good. I think adding a small rounded bevel to the top of the
liquid will give it a more realistic surface tension effect.

Something I whipped up this evening.

Awsome work on the model, composition and texture placement ! It looks
promissing.

You should separate the side and top parts of the glass supporting cardboard,
giving them different textures, just as a real cutout showing the darker
cardboard structure (probably some round form factored crackle (aka circcular
celled voronoi) on the side of the cylinder, but the lighter more grainy (rough
phong with large fade out) currently almost there should be reserved for the top
facing printed paper aspect. it do more justice to it by contrast. (if there was
one in POV (can't remember) you may turn that to Oren Nayar Blinn with max
roughness/sigma everywhere)

About the table, It's diffuse color value is somehow too high :it does not show
the lighting of the room / specular of the table come into play...

Finally some effects :

maybe some photons based caustics could happen if light came proportionally more
from a narrow focused spotlight.

As an ultimate final step, maybe the very minimal atmospheric media in the room
would add to this also as per Blender exporter default settings:
type 1 Isotropic 35 samples with a very dark diffusion color <0.001, 0.001,
0.001> absorption scale 0.00002

Don't drink and code! Programmers run on caffeine, not alcohol...

A few improvements. I'm working on it little by little.

The surface of the liquid isn't flat anymore, but it doesn't make much 
of a difference. A new texture for the desk.

Much better and natural now, I see the coaster is also improved.

Yes this liquid is much more nuanced and appealing. The scale of the new wood
texture seems too small : it features screws that we would expect to also appear
in a normal bumb, plus not reveal to repeat as much if bigger.

For smoked oak wood, the following page shows low reflectivity but the
interaction with bitmap is hard to assign. Maybe start with a grey material to
get the shininess right...?
