If there's something I would've paid money to know is the specific thinking and approach that Boulet uses for his watercolors.
I LOVE this stuff! It has such a beauty, richness and depth to it.
Boulet has posted numerous time-lapse videos of himself painting but it's not possible to see exactly how he does it. I must not have been the only one wondering because he's finally posted a video that not only explains the various types of water-based paints but summarizes his approach to "l'aquarelle" with the succinct term "La Gougoutte" or "L'il Drop."
This is "the secret" to Boulet's watercoloring success for FREE! AND the video has an English translation!
I tried this approach recently while painting my webisodes and it helped tremendously.
If you've struggled with watercoloring and are interested in a doable method, I recommend you watch Boulet's video.
