At the still-developing Regiment Games website, you can go to Gallery and see a few pix of painted Drantakhs. Larry Enoch has also come up with some captions that might give you some ideas for special characters and such in games.
If you go to Free Stuff, you can read a little story I wrote called Four on Four. This sort of relates to a couple of terms and ideas in the Two Hour Wargames 5150 rules, which include Drantakhs. Again, this is just to perhaps provide an idea or two for using Drantakhs in games, no matter what rules you use.
Website with new Drantakhs may be open for sales on Saturday.
