Questions of tact aside, Wolfman's observation is not without merit. Speaking form experience, it is all to easy to get caught up in endless preparation. At some point, you just have to start, writing, programming, painting etc. You can never anticipate every single thing you will need, every snag you will hit, everything that  may have to be redone in light of experience - those are inevitable. I still collect pieces for scenes I thought about doing years ago but I am a Poser dilletante with no real passion for art. Tebop, you have passion, imagination and obviously some degree of talent. Don't let your vision get submerged in obsessive attempts to have all the answers before you actually start creating it.That is not meant as a criticism, just a thought.
