Sometimes, if inspiration strikes, I can sit down and design a new model on the first attempt, such as the Hailfire Droid or Naboo Starfighter. Other times I'm trying for one model and end up with the paper leading me in a completely different direction - the Trade Federation Landing Craft was originally intended to be a Vulture Droid!
And then there are those models that persist in eluding me completely. I've had numerous attempts at a Slave 1, Y-Wing or A.T.S.T., but have yet to find an approach for any of them that even comes close. The X-Wing was another model I had to revisit several times, and it took 5 years from my first attempt to come up with the final model shown on the site today.
A trawl through wookieepedia gives a list of possible models I could consider making - There are some that I feel are absolute must-haves for the book, that are too iconic to leave out, and others which are not distinctive enough to warrant their own unique designs. I've marked up what I think my priorities should be, but feel free to let me know in the comments anything I may have missed or that you think I should bump up the list!
