How to change styling for the Tag Cloud

First of all, THANKS for this excellent theme. It is obvious that a tremendous amount of work went into its programming and its design. Flynn, you are to be heartily congratulated and I WILL be donating to support theme development when I can.

The only thing I wish to change so far, is the font size for the tag cloud. I'd like to reduce the font considerably so it isn't as dominating an item in my sidebar.

Any advice on how to go about this would be much appreciated. TIA!
