Pretty nice bridge camera. Glad you're stepping outside of your comfort zone. That's how you learn. Practice on things that aren't real important. By that I mean, everyday objects. Change the settings and see how it affects the image. Then when you stumble onto something really cool, you'll have a better idea of what the settings should be. That's what I've been doing and it's helped a lot. Not that I'm any expert, but trying really hard. Lol.
Not too bad with the crop. Are you using any editing program? A decent one could maybe clean that up a bit.
