Sadly you can't make skins in Caligula (though I am sure you have worked that out already), for that will you need a software title like Photoshop or Paintshop Pro.

You can use Caligula to add new units on the data file side though (which is also important to any mod). I made a guide to adding a new unit (find it linked in the link I gave before), and most likely you will be interesting in playing around with the data on the first tab you are presented with, as well as the weapon and armour tabs (a good place to start, it's the most straightforward).
