Nice job

Good One..

Nice!

I don't really think that your class is thick like this. In my opinion, if I explain your problems, and give some advices how to make better, you learn more, as if I make a comment like above, about how good is.

So I explain why isn't correct this scene, and you should remember my advises in the future.

The main problem is that everything is thick, this could be adjusted easily, just have to notice it.

The second problem is the sharp of the edges, use chamfer tool on every edges that are too close to camera.

Use texture on models, CGTtextures is full of textures of all the genres, and it's free. Nearly every texture has at least a minimal reflection, don't forget this, your floor will be much more realistic with a blurry reflection, under the right window.

Best wishes.

Nice concept and design, the render quality is good too. I suggest less desks and more details (books and pens on the tables).
and the DOF is nice too, Good luck Author.

very good render, i like the high quality of the render and especially the DOF is nice.
maybe take away some desks and show more of the room and add details.
good luck!

Very cool scene.

Very well done author!
