Side Seam Shaping

I've noticed on shirts 1, 2, 3 & 4 that there has been a little too much "frump" around the under arm section. And I felt it made my tubby physique look even tubbier - with shirt #5 I reshaped the side seam from a straight line into a curved line....below example 1 was the side seam used for shirts 1-4, while example 2 was the side seam I used for shirt #5.......

And here was the contrast and results of that change....a lot better!
 

and from these next couple of pictures you can really see that side seam shaping at work as the shirt is used...
