New Mod - The Nephilim

[moodgiesanta]

Hey folks, I'm currently in the middle of making a mod. It replaces Jotun with a race called The Nephilim, based loosely on the Book of Enoch. It's playable right now, and shouldn't have any huge issues. It isn't done, as I have to change some things and add several things.

Features:
A new pretender: The Fallen Virtue
A new race consisting of evil Nephilim Giants, twisted other Nephilim, human slaves and, of course, Fallen Angels.

Features I want to add/will add sometime:
National Heroes
Change to a couple of blood spells
A better looking banner
Balance

Is there a way I can use the graphics of an existing unit for a new unit? I want to do that for the national heroes. In fact, I don't really have any graphical talent, so I am pretty much out of luck for national heroes unless I can copy existing graphics. Also, if you are willing, I would appreciate input on balance. Actually I'd appreciate any feedback. There are some strong units in this nation, but there are also issues of supply, compounded by the lack of assured nature mages. Also that Fallen Angel unit is really, really expensive. (One of the pressing issues is increasing the cost of the blood spell to summon the Fallen Angel substantially.) Still, I think the nation is overpowered.
