Set of little galaxy things. Having fun playing with watercolour may be looking into gouache as well. Not much else to say here. They take a while depending on the colour and how many times you have to layer/go over it to blend. I find the lighter coloured ones a bit more difficult. Tools:
Sakura brand Koi Watercolours
Dynasty "Black Silver" flat brushes in size 12 and 20
Curry's Round brush in size 2
Anyway lots of fun nonetheless!
