3 Questions About Review Button

1) It is possible to increase the size of the Review button? I would like to make it more visible.

2) Is it possible to change the colour of the Review button? Again I want to make it more visible and so it matches my site better. Currently it’s grey and quite to see.

3) Is it possible to change the colour of the review start?

Any help with these 3 much appreciated.
