My first painting

This took me about two and a half all up over three sessions - I should have done four I think as the paint was not completly dry one time. I found the sky and the water the most challenging to make look realistic. I have to get a few more paints as the blue I had was not great imo. Also I need to learn how to mix colours! I used black to darken and white to brighten but read that you don't necessarlity do that!? Whoops. Anyway thanks for the lesson Brigitte! I can't wait to come back and do this painting again after I have done some in person lesson next month :)
Update: I added some things based off of feedback. Got to a point I felt I was messing up what was already there so called it a painting. :)
