Dude, this is fantastic. My degree is actually in Fashion Design, and I think I ever made myself one shirt. Collars, button holes, getting the armcye the right shape, easing in the extra fabric... it was all just too much of a pain in the ass. But you have really nailed it here. Except the cuffs on the black one, every one of these shirts looks great. Can you update your post with more photos of the details? Inside seams, collar, buttonholes, etc? You really have accomplished something very cool here, and by continuing, and refining your skills, you will ALWAYS have the ability to do this from now on. Imagine going to a friend's wedding, wearing a shirt you custom-made for the occasion! So cool. Big congrats, man. This is no small accomplishment.
