Yes keep doing your dream journal. Some people stop after a while because they feel it is unnecessary, but lots of people start it and don't stop. More lucids will most likely help you improve the length of the dream and the quality, but doing some work will help a lot. I would look in the dream control section of the forum here for tips on controlling your dream, and I would look at this thread for tips on how to stabilize your dream and allow you to stay lucid for a longer time . If you keep working towards getting lucid, then more lucid dreams will come for sure!
