GoPro Lens Replacement

When I am riding I like to film and photograph the rides.  Sometime early last spring I managed to scratch the lens on my Hero 3 Black.  So, I ordered a new lens and then dissected the camera and installed it. I then had to order an HDMI cable so that I could view and focus the camera simultaneously.  

I am still not totally satisfied with the result but I guess it will do. It would help if it had been sunny today so that I had a fair comparison.  The vid on the left is pre-HDMI cable and the one on the right is today.  I think I am fairly close on focus now, what do you think?
