Are the numbered panels actually doors or just segment designation? IMO the raised back end is really odd looking, but I really love the midsection w/ the 'ribs' and the front opening :3 Also, are those weapons pods on the side or additional engines?
Great stuff. Your well-balanced modular design concept is exactly what's still missing in the shipline of Eric Robert's forthcoming Star Citizen MMO for PC (the most exciting sci-fi game project in years, if you ask me). Did you know they have a "modder's corner" where designers can show off their work?
