Been doing this whole Blender shtick for about 6 months now, and only within the past month or so have I felt confidence to go out on my own. The most recent class was by far the biggest thing that pushed me in that direction. I’ve been doing Blender almost every single day since February, but my time varies wildly from 20 minutes a day to ~10 hours a day, though I’d say that 4 hours would be the average.
Don’t get me wrong, I’m by no means great, but I at least now have the self assurance to look at something and think “Yeah… I could probably model that,” with bad topology admittedly haha.
You should really join the upcoming class, it might be considered a bit basic for you considering you already seem to know your way around Blender but you never know what you might learn. Also do be careful of tutorial addiction, constantly looking at courses and thinking “Ooh I wanna do that!” and end up abandoning or stalling what you were previously doing, it’s a problem that begets many of us but it will only leave you being confused and demoralized. By all means experiment and check out different things, just be sure to moderate it.
