1. 20 (somewhat simple, its not bad, just not complex)
2. 19- good job!
3. 10- perfect color for stealth
4. 9- i see the function, but i wantz gunz! still, very good.
5. 10- very plausible
6. 10 fits in water duh
7. 10 stealth ops boat
8. 5 fits 3 whoot!
Personally, i liked this creation, but it was a bit simple. i had to knock you down because if someone makes a giant 4 foot boat, they should get a chance to do well and maybe win. though i doubt it, this one is good!
EIDT: total is 93
