Yeah, I really just use legos from my old collection and assorted parts. Mostly fighters and ground craft (tanks, walkers, etc). I have a few that i'll put up soon, but i just need to upload the pictures which takes forever because my computer sucks... I am building a few more now, but its slow work, especially after the completion of my Katyusha v1.0. If anyone knows anything about this "alliance" stuff, please contact me by reviewing one of my creations.
