As always instead of investing a lot of time in modeling all elements (helicopters, the ship...) I imported them from www.http://tf3dm.com/ so I can focus on the scene itself. I did modified the helicopters (It is a Mil-Mi 24 with Apache's guns and hellfire missiles), and added a few things to the ship (I modeled, textured and animated guns).
As always, there are some things I did well and some that may look a little off. I'm extremely pleased with the end product. It appears the battle happens at a cold sea and one might not have guessed I recorded this at a bright, sunny day in Santa Monica. I'm also pleased with the dynamics of the video, details (like water splashes), and the sound. One thing that kind of pokes my eyes are the smokes the erupt once the helicopters are hit. This is due to lack of smokes and fires in my library. I created the three smokes in pyrocluster, and while I'm fairly satisfied with the smoke itself I don't think it looks quite realistic in the video. Generally speaking, my library of sounds, smokes, fires and particle explosions is very thin at the moment. Hopefully I'll grow it to make future videos even better.
Here are couple of still pictures so you can compare the effects before and after I modeled and animated this video.
