The processing turned out well, but you completely misaligned the mandible and skull. Lucky you used a glue gun because you can release the glue and reset. You can see in the top picture where the cheek teeth (premolars and molars) do not line up between the mandible and skull. The lower canines (cutters) go in front of the upper canines (whetters), not behind. Looks like you have the lower canines pulled way too far out of the mandible.
