Congrats!
RCs have never worked for me...I get a good number of lucids per month by having the good luck of entering the dream lucid without being prompted by anything.
My first lucid was a WBTB one in the early morning, and I'll always remember it because it was so clear.
At first all I could hear were voices speaking in some weird language, then a picture came into focus of me sitting around a campfire with three people. The fire suddenly grew and the forest around us caught ablaze. Panicked, I turned into a bug or something and flew away until I was floating, weightless, above a greenhouse watching some 1940s looking teenagers walk home from school. Then I flew to Kroger to go hang out with my friends (?) where I touched all the food and commented on how real it looked. Then I accidentally wandered into an S&M shop and got so weirded out I woke myself up.
