Thank you for such a detailed opinion on that! I agree with you that it is not optimal to start right away and that the first project is going to be a small test game. I'm okay to redo parts of it, since making games is iterative process anyway. I plan to use 3D graphics where applicable, so it doesn't mean I have to redraw everything (at least that's how I imagine it). Of course, having 3D means there's more to learn, like rigging and animation, hence I'm okay to start soon, rather than wait until I'm good at everything (it might never happen). If I can achieve "good enough" level, I'll be super happy.
