Looks awesome!
So I don't really know anything about the ANH vest, but I'd like to lend my advice as it relates to the ESB jacket and the Dawn Anderson pattern. First, if you're starting from her pattern and have modified it to make that vest, you're more than far enough away from the source material to distribute your result however you like without moral dilemma. Second, I really don't think the vest is unlined. I don't personally see any evidence of a bias binding at the armholes, if anything there is a facing there. I would make it fully lined, though. In regard to the pockets on the Anderson pattern, the gussets she designed for her pattern are far off from what the actual pockets on the ESB jacket look like. Again, I don't know anything about the vest, but I can say that much about the jacket. A final note on the pictures of you wearing the vest up above, I noticed that the vest appears to hang away from your body a bit at the bottom of the front. You said you removed quite a bit of material to slim the waist, but did you add a dart to the front? On the ESB jacket, there is a dart hidden underneath the center of each bottom pocket. It's not big, maybe around 1/4"-3/8", but it would make a bit of a difference in that regard.
