Art concepts are presented for water in these videos as to shape and form and are suitable for all media and levels. I would suggest to view the Preparation Video first before trying any of the lessons, after that you can watch the videos sequentially or not, it's up to you.
Using your own reference is encouraged but not required. For the demonstration videos I have provided reference in the download tab under the video. Most of the videos have a reference photo shown. A few videos encourage you to use your memory and intuition, make sure you try this fun exercise.
