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.
