I agree with njeneb,
Don't give up! If you had fun with the model, keep at it. As someone pointed out, Blender is free.
I must warn you though, it's fun, and crazy at the same time. Making a model that blends into a TG2 environment is one of the most difficult things you'll ever do. You can spend hundreds of hours working on a model, just to have it overlooked by your peers, but that shouldn't keep you from working at it if you enjoy the challenge! It's up to you. I've been working on a couple of Walkers and neither is up to snuff, for TG2. But that doesn't stop me..
You may think this AT-PT-Walker WIP looks nice. Blending it to TG2 is a 2'nd and 3'd project in itself.
Just so you know, and everyone else that downloads all the free models, and pay for views.. A lot of work, went into and behind, your hours of TG2, placement..
Sorry for the rattle..
