No problem, you can definitely progress faster if you spend more of your available time on it, I did production off and on, sometimes switching to DJing instead or switching to other hobbies for weeks at a time. I feel like only now I'm finishing real songs.
There are many aspects to music making, it seems like right now you are just focusing more on the timbre, which is fine. You probably should keep going with that for now and just go on to whatever seems most interesting next. I find if you go with the aspects that seem most fun/interesting first this will feel more like a fun hobby or game rather than a chore. Once music making feels like a chore/work is usually when people give up. For me Music Theory was the least interesting - I'm just finally learning that aspect now! Some other things you'll likely need to learn:
- Music Theory, Melody, Harmony, & Chords
- Song Arrangement, Tension & Resolution
- Mixing, Mastering, Effects, & Modulation
- The individual software packages themselves
- Equipment & hardware
There are many ways to learn so you need to go with what feels comfortable for you. For me I started with free videos then later moved to paid subscription to online video tutorials from http://groove3.com.
I started with free classes at Coursera and can highly recommend the ones from Berklee College of Music that are available for free. Here is a great course track: https://www.coursera.org/specializations/electronic-music-production
This is the class that I started my journey with, it's part of that course specialization I previously linked and it's fantastic (and also free): https://www.coursera.org/learn/technology-of-music-production. After you complete this class your knowledge of what is going on will dramatically increase.
