Well, first off I dont understand why its only rated 5,5. That said I have some issues with it aswell.
1st, its looks "short"... not sure but it slooks like a dwarf :)
2nd, the weapons are awfully bulky and squarelike... in lakc of a better word. They could have been nice with some more round and pointy edges.
Paint it wel and I'd guess its a 9 or 10. for now; 7
