Head: MIS Star-Lord
-I removed the cap, and sculpted the hair using apoxie.

Body: Fandral
-Removed the chest plate, and added some apoxie sculpt as well.
I've been on a lookout for this for quite a long time for my Star-Lord custom. Never found a reasonable price for this. Good thing I was able to trade some fodder parts for this.

Belt: MU Capt. America, black garter strap

Coat: Paris Pursuit Snake Eyes
-Shaved off some parts of the hood.
Out of all the coats I've seen, this one resembles his coat the closest. From the strap across his chest, to the detailing, it really fits him.

Alternate Head: Fandral
-Shaved off some hair, and reshaped the face to make him look like Chris Pratt somehow.
As I've always said, I'm a big big fan of alternate heads! May not look exactly like Chris, but kinda works for me. That smirk reminds me of him though.

Guns: MIS Star-Lord gun
-I just removed the gun's extension and painted it to alter it's look. I then glued the removed part onto the side of his boots.
Though if you're going for accuracy, you can use the firearm from the Lego Star-Lord. It does fit him well. Unfortunately I don't own one so I had to improvise.
