well,
Ok your talented but, kick it up a notch! When your dad says if its worth doing its worth doing right.... for yourself, no jus get it done. but if your doing it for prestige (Resion I beat every video game I can get my hands on). DO IT RIGHT the first tip is get a better 3d engeine i have poser 5 tho that may be overkill for what your doing. But if you work with what you got;
1 MOST IMPORTANT THING: Personify the main character (in this your ship) that is, make it relate to your audience... thats hard its your job as the artist to get that one but your ship just flying out of a wall dosent do anything,
2 Try cell shading, i mean, look at wind waker BAD GRAPHICS!!! but its cell shaded so it looks cool SOME ppl like it but it definitely looks better than high-def low-graphics
hope this helps and #3(the one thats relly most important) KEEP AT IT you have talent try my tips youll go pro in notime... lol well good luck!
