I'd like to take all the credit for the DF Kyle model, but I'm afraid I can't. It's been a joint effort between myself and Infinity_Blade. It was started for the sole purpose of being used in the Dark Forces TC. I'm not certain of it's exact future either, as I handed all the materials I had back to I.B. to finish. So, if you're interested in the model seek him out on the Dark Forces Mod forum (

As for the other models, each one of them has their own reason for being unfinished. When I started modeling for JKII I had no previous modeling experience, but jumped in with both feet, as a result many of my earlier models have had numerous problems that I've had to go back and fix, and some of them require actual work, and I'm generally against that.
So,... I work on the models as the mood strikes me. often finding inspiration to work on a specific project and putting the others aside, until I'm inspired to work on another. Some of them, such as the X-Wing Pilot, are basically finished and are only waiting to be put into the game (which again requires work,... ). While others I'm just not happy with how they're turning out, and I slowly work on them in silence.
But rest assured, I'm still working on them.
