The following steps can be done in your own order but my experience says that this is a good order to reduce redrawing allot of stuff (Been there done that!)
You can use any drawing software you want but I recommend to do it in 3D!!
Any Autodesk software is free to get on there website in an educational version.
This doesn't mean you get less of it! It only means that on the side of your final drawings there will be a stamp on the side of the paper not crossing your drawing in any asshole way ;)
Also: Follow this project on my website!!
And go to "the vardo" for the gipsy wagon and "stories" for regular adventures.
I am actually going to build this and on my website you can see my step by step progress!
If you are not inspired or not willing to really do this then just don't do it!
Watch movies: black cat white cat, straight story, tiny house the movie,....
