Hello Friend.
We[[, you surely have a dreat deal of good advice from those who have posted. Taylor S's idea of simple is fine, if that's what you wish. Not for me, because I wish to stretch, artistically. Study, obsessivly all the guns in RCA. VOLs I & II. Draw every one of them which attracts you. My book can give you some ideas of 18th Century art forms and how to design them. B asically, my advice is to study, learn, and then, do your own thing. Good Luck!
