There's not much to say. This is a very poor image. The lighting is uneven, the composition is flawed. The colors are wrong (too much red). The focus is not sharp, all details are lost.
#1 Do not point your camera lens directly at the sun. It's bad for your eyes. And it will damage your camera's highly sensitive light sensor.
#2 While you are learning, take photos during mid-day when the sun is directly overhead or slightly behind your shoulder.
#3 Good Stock images begin with a good camera. Learn how to use and take care of your camera equipment. It's a big investment.
#4 Take some photography classes and join a photography club where you'll get feedback from other photographers.
Good luck & have fun!
