This was fuuuuun! Each style has its unique charm. Hard to choose a favorite one because they all have potential for different kinds of projects, but the one that made me more "woaaah" was the glazed tree. I love glazes even if I don't include them much in my projects. The figure 8 was satisfying because I love practicing that with my calligraphy drills. I made a super wet on wet and then a proper one but I realized I liked both, the super wet one makes me think of children's book illustrations.

I chose a metallic pen for the figure 8 tree and added tiny details with coloured pencils because I want to use them more with my watercolors and to add a bit of contrast:
