Hello and welcome to the forum.
You have come to the right place for all things SCI-FI. We have many member here who are greatly into SCI-FI (me included).
If you have any photos of the models that you have already built, by all means, please post them.
When you start a new build, posting a build thread is a GREAT way of showing off your skills, talents, and techniques. Not only that, but build threads are a GREAT way to show areas that you may be having problems with or highlight a solution that you came up with to a particular problem on a model.
If you have any questions, comments, concerns, need help, or advice, please feel free to ask and we will do what we can to help (or at least point you in the right direction).
Once again, welcome aboard. I look forward to seeing your work and I hope that you enjoy yourself here.
