Thought I would put in some of my thoughts as to why I voted for "The Ivy". Just IMHO of course, and all the builds are of such a high quality it is really down to opinion.
Jester: Very professional looking build, and love the neck laminates. Also like the way the neck is inlay free so that it highlights the binding and gold hardware. Not a fan of the colour for the top though, but it works well. Also the pickup cavity seems to be doubling as weight relief, not sure if that was the plan, but again not a fan. Still looks great and wouldn't look out of place next to other PRS guitars.
Decadantjon: Great work on the inlay and the colours work well together. Like the figuring of the wood. My missus liked the pickgaurd shape as well (I didn't, but she may have better taste). I'd prefer the body to have been stained darker, as it does seem cream and black which doesn't take my fancy. The inlay, while well done, also doesn't take my fancy.
Phil: I sent a pic of this too my brother under the title "novelty guitar/bass". It's well made, and is an achievement, but it feels like there are that many strings 'because you can' rather than for a purpose. Hence novelty.
Doug: I find that the figured maple clashes too much with the neck-thru woods. Nothing else strikes me as interesting with it.
Scottyd: Like the body shape. The LED inlays are a nice touch, as is the wooden bridge. The fact that a lot of the hardware is self built is good too. Not quite as novelty as Phil's, but still 6 strings still feels like 'because you can'.
