cool!
It was super nostalgic watching your video. Thanks for that! =)
I thought the lineart was great (especially on the ships - you could really see the details). I enjoyed the sound effect incorporated into each unit - esp the mutalisks ;) The scene where the muta picked up the marine was quite good and very original! I also liked it when the vulture reached the top of its parabolic path, sort of slowed down, and sped up again once it moved downward. It made it seem more realistic!
As for improvements, I think parts of the animations could be animated a bit more fluidly - for instance - when the marines walk around (could be a bit smoother). When the camera zooms into bird's view (that was cool concept!) I think a bit more detail could've been added on the hydralisk's skin (lineart for its spiney bone structure for example).
All in all, a great piece to pay tribute to an amazing game.
Well done!
