You captured the mood of 300 very well. And I like how they are all the same style, gives em the real "series" feel. You couldnt buy just one O.O
And the rays thing is totally right. The lighting typically used looks nice, but isnt all that realistic. Not bashing it tho... I prefer that type of lighting anyways, since most sigs are more fictional anyway. With yours being realism, instead of abstract, or having abstract effects, it works better to have that more accurate lighting. Very well done.
