My attempt at Photoshop

Hey guys I've been playing around with Photoshop trying to figure out how it works. I want to be able to make my own widgets, designs, headers, etc. so i'm trying to learn how to do all that. This is just an attempt on a picture I used i got from the internet:

I know it wasn't much because I'm still learning. If you have any suggestions or ways to help me with showing me how to make widgets, headers, etc. please feel free to comment below.
Thanks,
