I can’t see your pictures for some reason but give me a couple hours to get home and I’ll take a couple photos of my Emondas seat tube so you can compare.

Everyone seems to be saying it's fine, so I'm going to put my mind at ease and just stop worrying about it. The picture BluFalcon is offering will help put my mind at ease even more.

Thanks! If you use a flashlight or the flash on your camera, do you see any vertical lines on the front or back of the carbon seat post? I see a lot of horizontal lines on your seat post, but not many vertical lines like I have. Do you have two vertical seams on both the front and back?
I have the vertical seam on the front and back of my seat post, but there's a second seam right next to it that was the one that worries me.

First off let me say this. Take it to the shop, let them look at it and reassure you that it is fine.
The reason you see all the different edges in that area is because its a junction. Seat tube , top tube, seat stays, and seat mast, all come together right there. all the different layers are intertwined together in a mold under vacuum and heat. there are quite a few layers of different carbon sheeting that go into each frame. All the edges get staggered. That way you don't end up with a stress riser built right in. On a lot of bikes the junction areas are made up separately and joined together with different tubes in a jig, to make up the frame.
Google how carbon bikes are made. its pretty cool to watch.
