Rushed or not, those look great!
Nice, clean-looking warbands! They certainly show that as long as you keep the colors "in between the lines", you will get a good-looking warband! In the future if you want to enhance your painting with minimal effort, I'd suggest drybrushing some select colors, mainly metals hair or cloth, though you have to do this first as it can get messy. Another trick is to use shades to tint colors a bit, such as using agrax earthshade or nuln oil to darken down parts of weapons or armor. Both methods are very quick and don't require much accuracy. Of course, drybrushing and hence adding more definition to some areas of a model might make orther parts look bland..
I'm going to go with orange orcs as well, as soon as I get those models!
