That's happened to me before too I'm trying stuff out for the first time and sometimes it's decent, most of the time its not lol but given your talent I'm sure you'll make something even better soon. Keep at it! Even though all your art looks perfect to me XD
This is a totally great first watercolor work! The colors are amazing, as well as the poses of the person(s). I like the "clouds" and the "wet ground", the "rain", ... And once again one can see that rain can be so beautiful! Furthermore, the title says a lot, you can not always wait for better weather, just go outside and enjoy life!
