Just some watercolor doodles I've done over the past week or so.
The lightning bolt was done with masking fluid, but for all the rest, I used white watercolor for the white parts. I keep hearing back and forth about whether white watercolor is useful or not, so I wanted to try it for myself. I like how it worked with the cloud - it definitely isn't completely white, but it mixed nicely with the background color and I could build it up in some spots to achieve a nice range of tones.
The sketch in the upper right was originally intended to be stars, but I think it ended up looking more like a flurry of snow. I used the tip of my brush for that one, but for the lower right corner, I used a toothbrush and flicked smaller droplets onto the page. I had a bit of a leak happen, where a couple big droplets of white paint fell out of the toothbrush, so I ended up trying to turn the resulting splotch into a sort of galaxy background.
The planet was a straightforward little sketch, just with a bit more purple on the top half of the background and blue on the bottom half, with white watercolor on top for the planet.
The aurora was a challenge to do, because I wanted the background to be fitted up against it without white showing through, so I painted the background first, but that meant doing a lot of lifting to get the brighter values of the aurora. I think I overworked the page a bit. It probably would have been better to just paint the aurora and then paint the background slightly overlapping the edges of it.
That experience led to me wanting to try masking fluid for the next doodle - the lightning bolt - which I think turned out very nicely. I especially love the layering of colors that aren't quite blended, and the fact that I didn't have to worry about painting over the white spots gave me more freedom to play with the background.
