...which was absolutely an amazing journey!

Can someone help me, or has tips to model this shape

Hi everyone! I’m new to this community and just beginning my journey into surface modeling. After going through Nikita’s 6-hour course and a few other basic tutorials, I've started to learn a little bit about the workflow, and things are finally starting to make some sense. I’ve been working on this hairbrush lately. My ultimate goal is to model my own car at a 1:43 scale. I’m primarily focused on the exterior design—it doesn't need to be professional industrial grade, but I do want it to be clean and accurate enough for high-quality 3d printing. Since there are so many courses available, I’m wondering which step to take next. Should I jump directly into the car modeling course (possibly not)? Or should I go through more foundational surfacing courses first to get a better hang of the essential principles? Which courses are must-haves? I’d really appreciate any advice on a roadmap that could help me reach my car modeling goal without building too many bad habits along the way.

I saw this figure on Pinterest and i decided to replicated on plasticity, I try 3 times, is pretty simple but was challenging for my non-expert plasticity degree, but i get the final 🥳, at the end was really fun to do, render on Maverick Render.
