Mike, those of us who customized knives are often are our own worst critics. The work you did on that knife looks good. You did a nice job of hafting the handles and making them taper back to the center. The only problem with that is you lose a lot of the color and the jigging in the process. I prefer to have more of the jigging show and have the handle a little bit thicker, some people don't like that as much and would rather have a thinner handle. It's very subjective and up to individual taste.
The Camillus Streamline has very thin bolsters. They did not come with bone handles, they came with thin celluloid handles, it is rare to find bone thin enough to fit those bolsters and when you do it is usually pretty brittle. Celluloid has some flexibility so they can get away with using such thin handle material but even if you could get the bone as thin as the bolsters you would probably break it several times in the process of installing it.
If you look in my store you will see the Streamline that I put the stag handles on. Although I did not post a top view of the knife here in this forum, there are top views of that knife in my store. You will see that my handles are much thicker than yours, in part because it's stag and uneven, but also because it is very difficult to get natural material as thin as those bolsters and have it still retain its strength.
If you can find a spinner that works I would suggest learning to spin pins instead of peening them, that will save a few cracks to handles.
All in all, it looks good, much better than it did.
Give yourself a break, it looks great!
