Yours definitely does NOT suck
I'd just think about going back in with some green to give it more depth and take away the black. If you used spray cans you could still do a wash,but just have the mineral spirits as a medium and add the green to it and use a real tight celled sponge to go back in with green.
I personally think that the wash stage is what gives all the armor peices their depth,taking them from a 2-dimensional peice to a 3-dimensional work of art! It's also the hardest part because you have to really take your time and step back to look at it. I tend to do these steps on different days and at different times of day / night.Natural light is the best,but artificial light gives a different apperance too. I also tend to go back in with at least 3 washes. It REALLY gives depth to the stuff.
