Pretty cool.
Since you were asking for critiques, here is what I noticed on the first video, Calm Afternoon.
- I didn't like the diagonal wipe at about 35 seconds. I think dissolves always look better and are less distracting
- You show the torpedo running with the camera flying along with the torp. I would have used that with an actual hit on a ship. The running torpedo is very dramatic, and to not have it hit a ship seemed to be a little bit of a let down.
- Then you showed a ship passing directly over the sub. That felt a little out of place, because we just watched a torpedo run a pretty fair distance, now all of a sudden there is a ship directly over head.
- I think I would have switched over to the higher tempo music exactly with the torpedo striking the ship, then used a faster pace of cut scenes to give it more of a sense of frantic action. Maybe show a few seconds of a destroyer head on at high speed, then a few seconds of the sub diving deeper quickly, then the destroyer, then maybe depth charges launching (if that animation exist in SH4). Something along those lines where the action is back and forth.
All in all though, I enjoyed watching it. Will take a look at the others later today.
