Your second creation, the Three Story Victorian with Tree, had the ungrateful task of overcoming the first work, but surprisingly you did it amazingly well! It must not have been easy!
Thank you Marcos! There were a couple of times in the end, where I was getting a little burned out due to how long it took. (I have no idea how some folks can spend years on a project!) Most importantly though is the fact that I am passionate about this – as I am sure you and other AFOL/MOCers are. Many days it is nearly all I can think about. As such, it is the passion that drives. At a certain point, when I realize that I'm on to something and this could be really good, I feel I have no choice but to try and retry again until I get something as good as possible. Most of the MOC was built and rebuilt 3 or 4 times before I got what I wanted. This due in part to lack of experience, but also a drive and passion to create this thing which I have in my mind's eye.
