So the dragon is going to be more slender and streamlined than big, fat stompy dragons? That's good. I suppose its too much to hope that the head and the presumably long neck bob from side to side as it flies, given current capabilites (I don't know how clearly I have expressed myself here).
Perhaps there could be a few winged horses also, if you have got the wings working. There might be a problem with the height of the rider and attacking, so you might have to take out the horse first, then the rider.
After exams though, I won't be at home the whole time, as I am going away several times, so don't count on constant contributions.
I'm looking forward to being able to help, and wish you luck in the making of this awesome looking mod.
