Looks good! A few suggestions in both the modelling and the painting area.
Get yourself a hobby drill and drill out his gun barrels, to make them look more like gun barrels. Otherwise, it doesn't need much, except basing, which you should probably do.
In some areas, your washes are too heavy; In others, its non-existent. Water down your washes a bit more, and apply them a little more uniformly. Also, instead of using straight black wash, use a mixture of brown and black, to give it a grungier, oilier, more realistic feel. With a very thin wash (Watered down enough so you can discern the color, but you can see through it), give the whole thing a good once-over to sort of make the whole model feel a little more worn, and then go over it one more time once thats dry. Otherwise, the paint work looks good, except one thing- The blade. What you should do is paint it a solid color. Afterwards, give the edge a drybrushing in a lighter color, running the brush vertically along the edge of the blade, allowing the blade to cut between the bristles. This will make the edge of the blade a lighter color, as well as the area slightly past the blade, giving it a sharpened look. Right now its a little blotchy.
Also, it appears you did a blue wash to tint areas of the metal. This is a perfectly acceptable technique, but the thing to remember is do your brack (Brown+black) wash AFTER your tint wash, so the tint wash doesn't cover it up in areas where it shouldn't.
