Etoille Violette keeps going

Admittedly one of the better looking ones, there are several budding flowers, hope to show in extra. I spent the last hour playing with a fix it type app, and pleased to see I can do a mono with some colour, some practice needed perhaps advice? This is something I like to see on Blipfoto, suspect an iPad pencil will help, isn't it annoying when you can't lay your hand on something....
