Congratulations. I remember that feeling well. Don't worry, there are plenty more thrilling experiences in front of you. For me, my first solo land away was special and more recently during IMC training, my first time descending through cloud on a procedure and finding a runway ahead was also a great feeling.
One thing I can heartily recommend for your QXC, is to make sure that you set a waypoint 6-10 mins out from the field which you make absolutely sure you hit spot-on. The rest of the leg is then much less stressful. In mine, the wind was forecast from the north, but was actually blowing from the south. The west-east leg was extremely stressful until I asked a helpful Lincolnshire RAF controller for a bearing to her field (which turned out to be waaay different to what I was expecting). In hindsight, running a bit north of that first waypoint should have set off alarm bells. It does now.
