That's nicely done, but be very careful; files are brittle and can fail unexpectedly. As long as you use your newly made gouge only for spindle work you will probably be just fine, but don't ever use it for bowl turning. Not only is the file brittle, but you have a small tang going into the handle and that is a weak area. If you were to use the gouge for turning a bowl and got a catch, the gouge itself could fracture or the tang could snap off.
