I just start to use vray, please comment!!!

very nice. im assuming you mean its your 1st time posting with vray images. because for a 1st timer its pretty good. you must have had experience with other GI engines out there to get a grasp of it so quickly. The 2nd image is my favorite. The bricks on the balcony are slightly too uniform and look like procedural bricks. Using bitmaps for that would be nice and maybe a little displacement on the texture. And maybe a little imperfections in the floors wax job. (unless you paid alot to get the world best crew to do that wax job 
Very nice! I love the second image - I agree with Da_elf about the floors; maybe they’re a little too shiny. Otherwise, super job.
Well, I really meant my first vray renders. I just start using it for this work, I had a little experience with brasil, but just a couple of tries. I still need to learn a lot, mainly how to use and make materials. I just start using the forum as well, and for what I could see, I’m going to have precious help. Just hope my next posted render will mutch better. Thanks.

cool. always push your limits. welcome to the vray family
Thanks 
i will also agree with the previous submissions but there is another thing that you have to think about as well (offcourse this is my oppinion no affence always listen to other to improve) that is the camera wiev i have to say that all the furniture looks strange this is not a modelling problem strictly the camera wiev so try to play around with the camera a little bit i can say that the second image has the best wiev of those pictures. for the rest god job.
very good work. the second image looks like a photo. Great texturing.
Personally I don’t like very much the camera angle of the renderings (seems too low, maybe 30-35°).
You can use a trick; some times works fine:
Move the camera outside the room. Then in the camera rollout set the camera angle 40-50° and click on the “Clip manually”. Move “Near clip” untill you are inside the room.

da_elf, what do you mean with “imperfections in the wax” ?
blotches or to make it not so reflective ?
and the bricks are really procedural, but perhaps with a little bit more bump and noise and just a little bit of dirt and worn-out look they could be better for the purpose than a bitmap texture i think.
and maybe they are a bit too long?
you probably could use some blurry reflections in the floor…I think right now it looks too much like a mirror.

I agree with the camera angle, the furniture really looks funny, but I need a wide angle of the room, otherwise one can only see a very small bit of it, the problem is that the project that I have to obey has very small rooms, so in the right scale I have to make the camera view wider. I´m going to try Fabrizio tip, I think it will work, thanks.
Concerning the materials, they are all max material, because by the time I didn´t know how to use Vray Mats, and also the quality is not better, because I made a movie out of it, I´ll try to post it as well, or at list part of it, because it 3 minutes long.

How about these renders :?:

omg that first image is screaming for some vRay displacement, both with the grass and the stone. it would look awesome.
both images are nice…the second one has some nice dramatic lighting…it looks like its some kind of cafe or bar…in that case i would work some nice light fixture in the corners with the counters, it will help to establish the space and use of that space.
da_elf, what do you mean with “imperfections in the wax” ?
blotches or to make it not so reflective ?
Well anything from different values for reflections due to wear and tear on the floor and even bump maps, im sure the wax job was not perfectly smooth and the guys moving the furniture might have done some damage to it
om the second one, is there a vraylight on the ceiling?
No, just the sunlight.
I suppose psy was talking about the second image from the first post …
on the second image i the second group post:
I think stuff is "floating too much - especially the chairs - you need some hard, area or raytraced shadows to ground those objects down.
I think that will improve the quality a lot.
Paul.
Looks very nice.
Question: What type of glass are you using? In the interior shot when your looking through the window you see the clouds very washed out and almost grey. Are you using Exponential or Linear Color Mapping?
