Semi-final afternoon shot - Criticism appreciated!

Hello everyone!
Here is my latest image and as always I'm fishing for
criticism 
.
I did this in Direct Lighting Diffuse.
Image size is 2500*1250 pixels.
Image has 16000 samples but was clean much before that.
I'm using forest pack for the grass and Hdr lighting for the lighting so no daylight model from octane.
I used bloom and glare.
If you have any questions about what other kind of settings I'm using feel free to ask my dudes.
I'm using two Gtx690's and I'm not sure how long it took to render cause I was sleeping but it was probably somewhere between 4-6 hours or so...
I was thinking of adding a little something something in the back yard like a playground or something but I'm not quite sure yet so I'm looking for suggestions from anyone that has any.

Looks good to me, but there's something weird about the view through the large windows. It's like the furniture inside is duplicated. I'm assuming its that you have modelled the glass with thickness, however, is the thickness maybe too much? It may not be that, I can't tell.

8196x4096, 300-500 passes ( somethimes in DL 100 passes ), few minutes, scale it down and the effect will be the same. With Your video card I think about 15 minutes

Hey everyone thanks for the responses.
@merid888 I know the rendering time is insane... I'm not quite sure why. I'd love to chat!
@gordonrobb you're right about the windows and the thickness. I thought it was the reflection so I just put it down to 0 and I still had that problem. I'll take care of the thickness and see if that solves the problem.
@Jaroff I'm afraid I didn't really understand the beginning of your message. What do you mean by 8196*4096 and 300-500 passes. And what is Direct Lighting 100 passes?

By the way I just checked my scene and it takes 35 minutes to render the same scene but in an image that is only 400*800 pixels.

Octane says I have 12,832,042 triangles... Anyone think that is the cause for very long rendering time?
Also I'm rendering in 3ds max, not standalone

You right it's unclear

. Image resolution: power of two, 8192x4096px. Maxsamples 300-500 s/px in directlightning diffuse mode, not 16000. In directlightning Ambient oclussiom, sometimes 100 s/px gives good effect with resolution 8192x4096 . Next You need to scale it in PS, gimp etc.. 4x down to 2000x1000 and image will be sharp and ready in 15 minutes with Your video card.

So I tried doing what you suggested and even when I resample the image in Photoshop I can still see a good amount of grain. I actually found what was causing my render to take so many hours. It was some highly detailed useless geometry that couldn't even be seen from where my image was. I removed it and I'm now rendering an image with 4000 samples that should take only 25 minutes so that is a lot better.
Thanks for the help anyways!
