00:00: Modern Video - the Enterprise looks properly lit
00:30: Modern Video - kinda ugly, but that's inherent to the footage, as FrontierTrek mentioned
01:40: Modern Video - looks great
01:47: Modern Video - kinda bright, but the lighting is darker and more realistic than the original: http://tng.trekcore.com/gallery/albums/s4/4x10/theloss277.jpg
01:53: Modern Video - lighting is good, the shine is intentional
02:04: Modern Video - heavily backlit, but it's not overly bright
02:07: Modern Video - looks good
Out of those I only really like the shots at 1:40 and 2:04. All the other ones are far too hesitant in their use of true dark shadows the way CBSD uses them. Space is dark not grey and its this grey shadowing tone that makes the ship look flat and not properly blended with its surrounding.
Also the original lighting has not held CBSD back to massively improve shots with regard to shadowing. Those were the 80s they can do a lot better now.
