a little more zoom will do great impact.

I forgot to add, what you're asking with the zoom is not something I'd be interested in implementing but I can show you where you can find these values. 

Also, not too sure if you're aware but changing these values will mess up your artwork, particularly the type of left focused artwork you are displaying in your pictures!
