The "I Am Legend" poster really detracts from an otherwise nice piece

Make the top of the door as deep as the side.  The frame, that is.

The inside of the tv stand should be shaded to match the direction of light.  The bedposts should cast shadows on the blanket.  Same with the seat of the chair.  And the pillow doesn't look very comfy... 

But you picked some great colors and there are nice details in the room. 

Congratz great changes . Yeah, the bed doesn't look like it's messy, add another shelf to the table, also like skeddles said add junk, Whats that thing supporting the chair, also it look to skinny, make it wider.

Edit: Make the the shadow of the bed follow the wall.

Not bad. Glad to see it all iso now. May I make some suggestions?
Why is there a dead cat on the floor?
The blanket looks a bit odd. The highlight is too light, and its very flat(would you sleep there?).
Also, don't rush it. It looks like some neat freak tried to give off the appearance of someone messy, and phailed. WITH A 'PH'.  More crap, more. First off, its a dorm. Also, its s guys. I don't want to generalize, but most guys don't care about that whole 'neatness' crap. Add posters, pictures, shelves, tables, boxes, trash bins, closets. Crap like that.

I'd say its pretty good, but could be improved. Don't be afraid to spend countless hours on it.

lol... actually its a futon so it is the right size or close... and what doesn't have a shadow?

Much much better. There are incosistencies in the shadows. Some things don't have shadows at all. You need to really focus on the corners of things when making isos. Choose 3px corners or 2, don't mix them. The couch is out of scale, I think???? anyhoo...on the bright side the porn is still under the bed ; )

yeah i see the little places you're talking about .  I'll edit them... thanks for spotting them. =D

Huge improvement on the Dorm room...

Have to agree with skamocore about the lines though...The near edges on the door and the pinboard look like they have depth, but the far edges seem to be flush with the wall...

This is a massive leap forward from your last version.

Having everything fit within the isometric perspective has really improved things a lot, although...check over your lines there are still a few places where they are a bit off. Namely, the bottom of the door, the wall above the door and the blanket (the edge nearest to the door).
