Tony, very nice job on the blind fit! Also, very good idea to sew the track welt rope under the bottom edge of the blind to hide the vinyl from UV light and eventuall decay and splitting down the road... I like the roof re-work as well.
One suggestion, black anodize or powder coat the blind support stanchions and support rods. You might also want to consider filling the support rods with expanding foam and plugging them with some dowel rod inserts when dry. When dropped over the side, they will float and can be retrieved. I finally put thin strips of either gray or red relective tape from my deer hunting gear stash on the bases of my support rods to be able to distinguish which set is mounted in the aft receptacles and which set fits in the forward mounts. The strips allow me to chase them down in the dark, as well as when they decide to go for a "swim".
I really like the LED strip lighting use. I will be switching mine over to two red strips this year to minimize night vision loss when diving around inside the boat and rooting-out decoys inside the boat in the dark.
