Primitives excercise, snowman like suggested. 
Since people actually read these, as basic as it seems, I'm going to introduce myself.
I come from a photography journey that lead into photogrammetry during the pandemic and into the 3D world. There was no way around Blender so here I am learning properly (instead of the messy "follow a tutorial and get it done, but don't understand how" approach).
My mid-term goals (for now) are two:
1) I would like to create a cool shipwreck scene, with a 3D scanned shipwreck of mine but with added water and light effects, mainly lightbeams coming out of the pilot house. Static render.
2) I would like to use a 3D scanned reef scene and add animated fish and marine life, so kids in local schools (I'm based in Honduras) can have an idea what the reefs on their island actually looks like (using phones and tablets in AR), since there is no funding to take them snorkeling or diving.
Looking at my snowman and imagining my two goals, it seems ambitious. But that's what I'm here for.
Thank you for your support.
