I like to make Lego MOC's (my own creations), and sometimes it can be tricky to remember what a starfighter looks like. So , If I am making a Star Wars set ,I look at pictures of the ship in the movie and in Lego form (if it has already been made). It is also a good idea to build your creation on LDD (
http://ldd.lego.com/) if you want to rebuild it , but I think you should restart from scratch and you may be able to make it better. MOC's can let you see inside the mind of a builder. Do they spend lots of time on their MOC's ? Or do they just slap something together? It is also O.K. to use something small that Lego has already designed , like the Vulture Droid. MOC's can range from little kids making a car to an AFOL (Adult fan of Lego) making a minifig-scale Imperial Star Destroyer. However you do it , whatever technique , just try to keep it color-correct and minifig-scale. GOD BLESS!!!!
