I'm tackling a school project and seeking input from someone with expertise, if they have a minute. Does this effort seem satisfactory for a junior high schooler? Is there more depth to be added or are there specific aspects that need refining? What can I do to improve my modeling skills to better showcase this craft in the future? My primary concern isn't gaining praise but learning from those experienced enough to offer genuine insights on how to excel in this profession. If this piece lacks something significant, what's missing and how can I go about rectifying it?
