Excellent! I love that look. You really took the effect to the next level. Only thing i would do differently is that instead of just starting from bottom have it come from the middle. But that just me. Great job though.
I think your transition from normal to stealth is totally awesome. The minis are very well-painted too, from what I can see from the photo. I think it might be cool to paint some sort of grass or dirt texture on the "stealthed" areas to enhance the effect. Also, higher-resolution pictures would help. Remember, on this site there is only a width limit, no height limit, before images will be scaled down.
