This video shows the whole process of painting a competition level freehand. The video is long, but I think it is good to have it all in one place and I will gradually add a table of content with timestamps for quick navigation in the Youtube comment-section.
One of the most work intense videos I ever made - I hope it's going to be helpful and interesting! If you have any questions, as always, let me know!
