It kind of reminds me of the Chiram Ishkick from Super Dimensional Century Orguss. Sure, I'd have to chop off the two rail cannons to numbs and take off the wheels, but it does look like a Ishkick to me. Then again, I believe Shoji Kawamori worked on that series as well. I know that he didn't work on Sourthern Cross. Mind you, I still like your design.
Thanks dude. I do original stuff all the time. If it isn't labeled as Battletech, then it's probably original. Even a lot of the Battletech stuff I post was designed by me... but there are a lot of style rules I have t follow for those so they have a certain look.
