First of all I want to say congratulations on having a lucid dream.
You should know, that most of the cases, first lucid dreams are not that exciting, and it’s hard to control them.
Don’t worry, the more LD’s you have, the easier it will be for you to control them.
In the meantime, I would like you to suggest reading this nice guide about dream control:

Good luck on your future LD’s!
