I don't know a lot about Ed Sheeran. He seems like a nice guy though and I like that. I do love his song "Thinking Out Loud". I decided to learn it after it was tabbed out in a recent issue of Guitar World magazine - August 2015 if your looking for it. As millions of people already know it is a really great song. It is really fun to play on guitar and has some nice rhythmic phrasing if you want to practice muting on an acoustic guitar in a strumming pattern.
The chord progression for the main part breaks down to basically a simple I IV V change using D G and A major. This progression is the basis for thousands of songs. After I learned the song I wanted to try and come up with a melodic lick over a similar progression. The guitar lick itself is pretty easy but I like the way it sounds. I threw in a few improvised licks in between. Here is the tab for the main lick:
