Hello I'm Fahim Faysol, a student at Leeds Beckett University in UK. I was hoping to recieve some crituqe for my VFX sequence which was aimed to acheive a successful Matte Painting. Click the link below to watch the video.
As Glad has said before, Interesting project but I think you'd get better feedback in a forum not dedicated to Game/Realtime VFX. Best of luck!
Ouick tip: If your footage has camera movement, you need to match that movement on your background replacement.
And yeah, you would be better off asking in a forum dedicated to pre-rendered vfx, like here:http://forums.cgsociety.org/forumdisplay.php?f=414
