Congratultions on successfully completing your First solo flight. A day never to be forgotten. Now we can start to think about cross-country flying and then also logging some solo cross-country flying time.
P.S. I still remember my first solo flight; it was in an air force De Havilland Chipmunk WZ879 at R.A.F. Rufforth on April 27th 1967. (I have just checked my flying logbook). Only 41 years ago!
