Instead of matching the colors between the edge and center piece, I would actually put the edge piece over the other center (so that the UF and F center are the same color). Put keyhole under slot, and do R U' R'. I think it's more comfortable this way and the cube doesn't move around as much. R' F R F' is almost like a cube rotation in the sense that you end up with the U face sort of in the back. Personal preference, I s'pose.
As far as the tutorial goes, it was well explained. Nice job.
EDIT: I see someone already commented on this on YouTube.
