Decent.
Well, that was decent. Despite the fact that it all looks stolen from David Firth, there's actually some 'new' stuff in it. For example, Salad Fingers's mouth actually sings along in some scenes, which is a very nice touch indeed.
I can't give bad nor good points for style. It's not really -your- style, but I don't consider the style bad. Let's make that a 5 then.
Sound... Yes, I like the song, but once again, it really isn't yours now, is it? No, it is not. Yet you did pick out a good song.
Yes, I gave a zero for violence, interactivity and humor, mainly because it isn't really in there now, it it? There's no violence, it's not interactive, and not funny.
Though it's quite a nice montage, indeed.
