Just eyeballing the tracking results, it looks good, yup. The corpus callosum looks uniformly red connecting the hemispheres, the cingulate bundles are green (running anterior <-> posterior); the cortico-cortical fibers look to have appropriate colors (=directionality) at their endpoints; there looks to be whole brain coverage.

While looking at that tractographic image, if you go to the SUMA control panel (hover the mouse over the SUMA window and hit ctrl+s, to open it if it isn't already), then you can right click anywhere on the tracts to get the control panel for tracts, and in the lower left corner is a button called "masks"-- hit it once/twice and a faint ball will appear in the tracts, so that only tracts passing through it are shown. While it is translucent/dotted, it is stationary; if you right-click on it, you can turn it into "mobile mode" (-> its appearance will change and it will look like a geodesic pattern of connected triangles); now, wherever you rightclick on the tracts, the mask-ball will move, and you can look at more localized patterns to make sure you see things like: cortical-spinal tracts, genu/splenium, etc.
