@baukepost I also find the blockout part to be the most difficult, especially finding the right balance between “not to detailled yet” and “too basic primitive”.
You did a really good work, it was worth the challenge! Few comments, feel free to take them into account or not 🙂 :
– add holding components to the rear part of the cover frame
– the “what-would-be-the-fuel-tank-if-this-was-a-motorcylcle” could be elaborated a just a tiny bit more: more curve perhaps ?
Aside from that (and I think I’m being a bit picky), you should be able to have a lot of fun detailling this from this blockout!
