thats a pretty good composite... a few things, though: 1. it looks too much like video , and i don't think that was the look you were going for. deinterlace, pulldown to 24 fps, maybe reduce the contrast a little more, and some small film grain always helps 2. the reflections of the planes stood out to me .. i think they might be too light. also, shadows would be awesome (though difficult for this scene) 3. and i hate to say it, but the scale of the planes to the trees they are flying through -might- be off .. but it could be correct for the lens you are using..
even if you don't fix any of these things, its still a kick ass composite, and i dont think you have to worry about your grade on this project.
I agree, great composite work! But the reflections should be stronger. That's a very reflective lake. During the breakdown the reflected buildings and trees got much darker, yet the planes actually lightened up, almost a screen effect. Doesn't go with the other reflections.
In hindsight I think it was a screen effect. The breakdown shows that the planes were simply flipped, but what the breakdown does not show was that their brightness was greatly reduced to .1 of 1 (the breakdown was just so long and boring : )
Because of your keen eye though I'm going to go back and take a look at those reflections. Thanks for the help!
