I got a green screen muslin with the package too. Haven't tested it out yet, because I haven't been doing much video work lately. Not really my forte I think.
Btw, having watched the video, I've got to ask... Is the blurriness around your hair and transparency in the edges of your shirt a focus issue, or is it particular to the blue screen? I was thinking the focus was off, but then got to thinking that since the shirt and the glass were both in focus, you might be using a narrow aperture anyway... The result looks interesting. Might give it a try one of these days.
I probably could turn the blur a pixel or two on Da Vinci Resolve. BTW that is a great piece of editing software and totally free. You can adjust the blur where an object meets the blue to prevent any fringing.
