Nice enviroment. attention to details is very much apparent. i especially like the photoshpped sapce behind the background. nice use of plantings.

Cool Feedback:

At the moment I don't know really what type of ambiance you want to achieve, whether its daylight or night scene. If it is daylight scene, then maybe concentrate on it. maybe turn off the lights inside the house.. Second you have to consider the following:

a. Sun shadow, increase the sun size a bit in order to have softer shadow.

b. change the background, use a background (blue sky maybe) not like dusk background. match the sky with the lighting set up

c. Use displacement material with the pebbles

d. although i like those bamboo models in the warehouse, i think you need to change the material

Yep, specially the background. change that please hehe
no, really, i think your image will improve a lot if you change it
