I like 'em. But you know how I feel about Stambaughs. Your Stammies are different, that's for sure. If I didn't know better they could be a regularly available body shape from Chris. They certainly express your design intent. I like the wood choices and the inset wood pickguards. Even though the upper horn looks short, the strap button lines up very close to the 12th fret. Nice. I still contend that Stambaugh's headstock shape is one of the very best (possibly the best) in the business. It looks great regardless of the number of strings. If I owned the two basses in question they'd be played with pride. Of course, they are both missing a B-string.
As for the Fender mentality around here, it is what it is. The Valenti is surely a wonderful bass, but I couldn't get past the headstock shape. It reminds me of the Callowhill J(unk) clone and those A Basses that were around for a while. In fact, that's where many of the Fender cloners fall short, IMHO. In their efforts to improve upon or be different from the Fender headstock silhouette, they end up looking a bit awkward. There, I said it. So sue me! I could name many more and offend hundreds of my fellow TBers, but that can wait for another time. It's all in the eye of the beholder, anyhow.

And I would never pay boutique prices for a bass with a non-angled headstock and string retainers. Nope, wouldn't do it.
P.S. If you're ever tempted to sell these basses, don't. You will come to regret it.
