Looks cool, but if you want people to judge your project on its merit, then don't post information about your age; it will make honest feedback difficult both for you and the sender. PS: anyone who can keep their focus on a project for more than a few weeks and complete it can become a fine engineer so don't worry about that.
It's cool that OP is enthused by engineering, it's a cool little thing they made, and it's great that the next generation of mechanical engineers are starting out seeing software as a tool in their armoury. Those are the merits I can see here, and in my judgement they're all awesome.
