They do look great. You have the technique down pat! Your fit looks really good.
It does look like you have a problem on the Blue Swirl that many of us have run into - the adhesive showing through the material. Many materials are translucent when they're turned as thin as we have to tuern them. The solution is to color the tubes and color the interior of the drilled material with the same substance. There is a debate as to the bestr thing to use to color the tubes (inside and out). I use Sharpie pens - which I sometimes have to break open to use thoroughly - or fingernail polish.
You may have the drill a wee bit wider or sand down the tubes a little more than the normal roughing up so that they'll fit together once you get the coloring done.
I just share this in case you hadn't heard about this before. Hope this was helpful.
