I got 2 TH masks recently, which I was interested to try. The music one is quite large (this is on a 14x10" watercolour pad) but the compass is smaller. I played around with different acrylic paints and touched it up with a brush -
on this one I tried ink too. I'm not sure what I will use the music one for, but I would like to try some other media with them. The inaccuracy of the music is slightly irritating, if you're going to get someone to design something, then do it properly!
