Yeah ! It really looks better =) Maybe you could try to subtly darken the wooden plate of your door, juste the middle part to push in these volumes.
For me, this process is a lot of testing. Sometimes it works, sometimes it's crappy =x Maybe my suggestion will be crappy.
It's not really a AO, but juste a simple "vertical directional light" that you bake in your texture. You can paint it directly in photoshop when it's enough simple (like your door).
In general, gradient can also help to add more interest when you have large flat surface.

In my shot, the left side is your actual version and the left side is "my" version with a cheap lighting painted over.
I"m not saying that adding a lighting in any texture is TeH base to work with but it can helps when you have an object wich will always be placed in an unique direction. I find it emphasis some shy details sometimes.
I really like your frame shapes but maybe your texture should have a lighting pre backed, especially for your door ?

It's a bit complicated to fix the seam problem of the top border of my stairs since I didn't manage well the Uvs =x I had a bit less than a 512*1024 map to unwrap my mesh and I completly f*cked some part... I mapped 4 steps since I could make only 3 of them to gain some space. Now, I'm taking more attemption about that point because I tend to put unique detail non pertinent part =x
But again, thanks for the advice =D It looks now so obvious !
New object =)

froyok: that looks awesome! Howcome it wasn't succesful?
We are in the same school (HEAJ). And this school is very exigent with her student =x
I completly agree with you but these color addition will come with some foliage props and texture variation by vertex color. I thought it was too early yet at this stage 
Some new props !
The lighting is a complete test. I do not have any light or windows ='(

*_* Really nice lighting !
No problem dude, I didn't take it like an attack 
I can understand that purist could find it completly weird. I did it that way because it's much more interesting to see that kind of detail.
Anyway, I did other meshs for the bottom of my temple front.
I only show the diffuse for the moment. I'm not really satisfied with the shader =s I tried to give it a wet look but that not that simple for me ^^'

Nice metal ! But, I think there's too many bolt maybe ?
My turn : Some textures made for an old project Half-life inspired (only albedo ) :
