The only things I notice are that the timing text (00:00:03 etc) needs to be more opaque and slightly smaller - the BBC World box needs also to be a little bigger and further into the bottom left hand corner - and if possible the map would look more closer to the real thing with a purple to red vertical gradient.
It's already been hijacked so better to use your "everything" thread I'd have thought. Tis very nice, not sure how faithful recreations of that era can be given there's no images with a decent resolution to look at.
Advice: save your work as a .png if possible, .jpg files are horrendous to look at...
I wasn't paying too much attention clearly because now all I see is lens flare, tone it down a notch. And yeah, Malpass is right but not using as much compression when outputting JPEGs will still be smaller than an equivalent PNG.
