I think first and foremost...don't worry about embarrasing yourself. If you like what you build, that is all that really matters. For me, contests aren't about impressing people or expectations of winning trophies. I go to meet people, look at other peoples models, possibly pick up a tip or two and deals from vendors. Where I am located I don't have to worry about winning trophies anyway because of the quality of work I'm up against (Bill Geary, Lyle Willits, Irv Arter, Jeff Sauber, Cruz ...etc etc). My advice...go, have a great time, talk to as many people as you can and don't get hung up on whether or not your model is contest worthy. If you pay the entry fee then it automatically is "contest worthy". Good luck!
