Completely agree with Purdie. I've spent probably somewhere in the neighborhood of 300 hours in the studio and have never been completely satisfied with the final results. It's a very humbling experience, but it's just that: experience. Now that you've had your first session, you'll be even more prepared for the next time.
Thinking back to my first time (1989-90), oh Lord...it was my first time playing to a click, I couldn't hear it over my playing so the engineer used a cowbell sound and jacked it up so much it literally made my eyeballs shake with every hit, and it bled through the headphones into the mics! I was later kicked out of that band because my time was so bad. Nothing motivates you like failure, so I worked with a click for years to improve my time and for the last several projects I've been a part of, I play to a click even live.
My most recent time in the studio was 12 years ago. The acoustic guitar and vocal tracks had already been recorded, so I laid the drum tracks over them (very backwards way of recording, IMO). I was so off we ended up spending countless hours using the editing software to digitally move many kick and snare hits to be in time with the click.
It doesn't matter how many you do, every recording session is a learning experience. Your tracks sound good, that's quite an accomplishment for only 10 hours in the studio.
