The default, you don't need to set.
> assumed_gamma 2.2
> max_trace_level 30
Your scene don't look as if it needs that much.
> radiosity {
>  pretrace_start 1
It's useless to start at that level. better to stick with the default here. 
Default = 0.08 or 8% of the image's width.
>  pretrace_end 0.003125
Keep it at the (pretrace_start / 2^n) domain. Other values will be rounded.
>  adaptive 2
adaptive is megapov only. Don't works with the official version.
>  error_bound { 0.15 adaptive 1.5, 20 }
Using megapov only syntax.
Defaults to 1.8. A low value requires a high count value.
>  count 150
You may need a larger value here.
>  recursion_limit 1
You need at least 2. 3 would probably be beter. 4 may not be worth it. My 
personal experience don't show that much effect on the render time.
>  brightness 1.5
To brighten up the scene.
You can add:
low_error_factor 0.4 or less.
It lowers the error_bound during the last pretrace step by that amount 
(error_bound * low_error_factor). Default to 0.5

To get beter similarity, use a sky_sphere or large world sphere with a gradient, 
blue at the zenit and pinkish near the horizon.
