Hi Newb - I don't know if I would say you failed. As an abstract painting, this works very well. The colors are nice and bold and the picture grabs ones eye. If you are trying to make a realist type painting, I think that the sun is too 'spiky'. You should soften (blend) these rays down so they are like a haze. The horizon needs to be level to be realistic, and if the foreground is water you need a long reflection of the sun on its surface. As Bob Ross says "We painters don't make mistakes, we have happy accidents!". By this I think he means that we may all start a painting with one thing in mind, and wind up with something we never expected. A failure would be not doing any kind of painting!
