you asked for opinions so i’ll give you mine 
the fact that PS3 XBOX2 GC2 are all coming out soon doesn’t mean developers will look at throwing around polys, look at GTA vice city its a huge low poly environment,
I would include the character in my demo reel, as its a fantastic model thats very nicely textured, and if its about 4000 tris then it is relatively low poly. but if you want to be a game modeller like i do i was advised to have models varying from 700 tris to 5000 tris in my low poly section, and show that i dont need masses of polys to create good game art. the advice was from an ex acclaim employee so i’ll go along with it.
hope that helps 
Oh and a bit of crit, after looking at your textures closer, I noticed the zip doesn’t have the same size zip bits all the way up the jacket.
