Very nice work there TM2YC, and what a difference compared to your early test clip on the 1st page!
I'm really interested in a lot of the ideas you're doing for this, so I'll stick up the original titles below, as I have a couple of thoughts for you to consider -
1. The new VENGEANCE re-title fits the movie well, but I think that the size of the word in your clip seems to make the words STAR TREK look a bit small in comparison. Of course, it may be that you just prefer the VENGEANCE letters to be more front and centre, but if both lines of text were laid out in the exact same 'width' as the original version, then the STAR TREK letters would look a bit more prominent overall.
2. I've got to be honest, and say that I like the way that the STAR TREK letters appear first in the original version, before we see the text below...and reckon it might be worth trying to have your VENGEANCE letters appear around the point that the STAR TREK letters 'shine' into full view, in a similar way to the timing of the original titles.
3. Also, I wonder if it would be worth doing the VENGEANCE letters in the exact same surface colouration as your STAR TREK letters
(at the point they 'shine' into full prominence), rather than the 'cracked' surface detail...or alternatively, to just have the VENGEANCE letters be totally 'white' instead.
4. Lastly, it might be worth trying to fade out ALL of the lettering at the exact same time, like the original version too.
I'm liking your 'lens flare' additions in this, by the way, and the 'starfield' works perfectly.
However, if you prefer to get away from the overall look of the original 'Into Darkness' titles, then just disregard these comments.
