Here's another small update.... I remade the bit going around his neck, and also added some quick straps and belt.

As T1ck pointed out early on, he is looking a little unbalanced - I am hoping to pose him leaning forward, though I may have to redesign the vacuum.

At the moment he is just under 6000 polygons, though there is probably some unnecessary geometry in the vacuum - especially the sphere - and I haven't really deleted any hidden faces such as his feet and hands.

any comments / crits ?
