Much of this is nitpicky and about consistency, nothing is super crucial.
On the comparison gallery, why did you give the 2011 the prime upper left spot? If you want to showcase your contribution a little more could on future iterations switch to a layout where the new version is v2.1 full size, and the other (three) references are smaller and underneath in a row. But understand the idea of giving each release the same resolution/real estate.
In the bottom line, at first 'Remastered' didn't mean anything to me until I saw it as well next to the V2.1 pic. If it's easy, whenever you use 'Remastered' add v2.1 next to it.
The descriptions of the four pics gets lost at times. Maybe a harder drop shadow? or a transparent background box. (can continue the blue theme) Also (2004 master) vs (1993 Master) capitalize or uncapitalize.
00.15 : "and now recedes at the correct speed.a" [add 'the', remove 'a']
In the whole shot, the HD background starfield is a combination of an enhanced BluRay starfield and a 35mm frame scan, because in the SE the starfield was shifted up. Slight gate weave was also added to all elements. [seems wordy how about]
The background starfield is a combination of a BluRay starfield and a 35mm frame scan. The starfield was returned to it's 1977 location. Gate weave was added to unify all elements.
Under Sources you mention the 35mm frame scan, and in the description is mentioned the 2011. Is the 'Sources' category suppose to list everything or only the additional material past the 2011. If that's the case maybe call it 'Additional Sources'. The 2006 is just as official as the 2011, i'd cut the 'official' word.
00.44 : D_J's version is mentioned in the description but not in the Sources.
The description is tight to the lower left, can expand the text window to fill the box on the right side.
00.52 : Dark_Jedi's 720p upscale
01.44 : DJ's GOUT DVD.
Work out a consistent naming system or have the first one be as descriptive as possible and in (shorted name) there after. But you'll never know who will use what images so the full name might be good to use at all times. I noticed you don't call the 2006, GOUT in the Sources, will GOUT only be used when talking about DJ's release?
There are Source variations to the names:
02.27 : HDTV 2004 SE
02.45 : HDTV 04 SE
I'd lean towards a standardization of Movie:Release Type:Year:Format:Release Group
so SW SE 2011 BluRay, SW SE 2004 HDTV, SW 2006 DVD, SW SE 1997 Reivax, SW 35mm Frame (or Film) scan, SW 1993 LD Japanese, SW 16mm Puggo Grande
