im sort of on the fence with pulling you on for trial. its really depending on how serious you are about improving and commitment to the mod really.
ill give you a chance to show us what you can do though. go ahead and make a new thread in the trial members section, and we can get you something to make.
i think what ever it is that you make, your going to have to take all the way from blank canvas to fully textured model though, cause im not so sure your familiar with game resolution modeling yet, so ill want to see how you do with modeling and texturing.
