Hello there,
I've seen your sample video it's a bold and graphical film, I definitely can help you to eliminate those problematic green screen shots! (ex. shot with girl at 1'45") I would love to further discuss with you about how we can done this. I'm very experienced in video compositing and keying, with more than 10 years of experience. You can check out my demo reel: https://vimeo.com/39037630#t=16s I've embed the time stamp (0m16s) link to the specific part where I demonstrated a film I shot, keyed and composited, all shot before green screen. Please also check out my portfolio under my profile, though I'm new to Freelancer.com, I've already accumulated several good portfolio in the past, which can show my true ability.
Before we have any further discussion, I want to let you know what I have in mind for your project now. I will ask you what kind of backgrounds you want to put on, because the color of desired background will affect how I approach the green screen keying. Especially for the girl shot with problematic hair at 1'45". I will update you with my progress frequently, make sure everything is what you want.
Let me know what you think, I'm looking forward to talk with you about this project!
Cheers,
Allen
