Hi,
I was trying to make droplets of water on a plane and finally made this
whole scene. But there is something I dislike and I don't know what, do you
?

Looks very nice! I think it could use some radiosity though.

Are those water drops *supposed* to be star shaped? I suppose so...I
don't see how that could happen by accident.
Hmm, the bottle doesn't seem quite right...give it a slight surface
normal and an ior if it doesn't have one. Wrinkles should give it a bit
of unevenness, like plastic or glass bottles usually have...you normally
can't see through them without distortion.

The water drops don't appear to be refracting the surface below them.
Try adding an ior statement or increase the value you used.

Same as i thought, you could try some reflection too.

They don't "wet" the paper in way.

Try this for the water (i have made this finish from scratch...must be better
than your actually):
finish {
phong_size 220
phong 0.2
roughness 0.001 //or try a smaller value
specular 0.8
reflection_type 1
reflection 0.2
brilliance 3
}
and the interior:
interior { ior 1.33 } //..i think you are using this already

well, they effectively are, but actually anyone seems to see that drops draw
things on the table :\ but I know how to correct this ...

for the wrinkle you're probably right but I don't agree for ior cause the
bottle is a plastic one and it seems to me that there is no distortion with
this material, or am I totally wrong ???

yes I've thought at putting water on the real paper sheet I've scanned and
finally didn't do it but it would be easily to make it ...

I noticed some other odd shapes, but they didn't make much
sense...something that looks like a moon to the left, some pretty odd
formations in the back, a pair of "somethings" to the right of the
moon...

You are wrong. Take a bottle and look closely at it: objects seen
through it appear slightly distorted because of the variations in
thickness and surface features. The distortion isn't much because the
material is so thin, but it is definitely there and could give a lot of
dimension to your bottle.

I see a palm tree, a star, a bikini, something resembling a fuzzy hat or a
truffle or something (over the word project), and some large fancy
indistinguishable shape in the back.

Hmm, if you see a palm tree(I think I see one on the left...my "moon"
was a leaf) and a bikini, the stars are probably starfish. A hat? Maybe
some kind of shell...

yes that's it except for the fuzzy hat wich is nothing particular, but I
still admit it isn't really viewable ... the shape in the back is waves, I'm
going to change all of that in the next release

as said on the french povray news, it could be a good Rorschach test isn't
it ? ;)

I'm not exactly sure how to model paper that is "wet". I think a
numerical approach to some viscous fluid flowing via capillary action
within a fibre based substance would be required. On the other hand an
exact model is rarely required for artistic purposes and maybe just a
grey region around the water puddle would suffice.

In MegaPOV, you could use the "object" pattern to make the areas covered
by water a different color...an exact simulation would definitely be
overkill for this.
