Pedro,
John's advise is very good. Experiment! Sure, you might make something
that at first you might not like but examine what you've made and ask
yourself "How can I change it?" Then again, you'll make something you'll
love one moment, come up with a better idea, and junk what you once loved
(its happened to me MANY times!)
When I constructed my first suspension bridge from Technic (sorry, no pics
on brickshelf), in West elevation view (seeing its span) it looked OK. But
in North elevation view, I thought it was junk. So I just tinkered around
with small Technic parts like triangles, lever arms, etc., and pulled off my
Trademark Bridge.

(Like I said, at first I loved it but now I want to build a better version!)
Geometric triangles (3-4-5, 5-12-13, 7-24-25, 9-40-41, 11-60-61, just to
name a few) only go so far. Apply that LEGO builder instinct of yours and
you'll come out better!
