Thank you for your feedback. Unfortunately, my colors don't seem to blend well, same goes for glazing, so I mostly use pure color options that I have. Maybe I just need to practice more, but my paints don't blend like what I've seen in the watercolor lessons online.

I don't use any masking fluid. About the water, I don't know, I just use a lot of water to keep it from drying too soon, and work really fast I also do some retouching after to fix little mistakes and edges I don't like, in Photoshop.
