Wk13 Blue-Screen Fail, New mask & Reshoot without Macro

I'd decided to stabilise a shot of an eye then using the tracking points of the panned mask, move the eye with the mask, making it look like it was originally with it.

I've decided that my idea to use a blue screen effect isn't working thus I made a new mask just for the eye shot.

I then decided to reshot the eye using a standard lens then zoomed with FCP and removed jitter... I'm not liking the pixelation.

I think I'll have to reshoot using the macro lens...
