Hi Steve:
I wanted to post earlier but just too busy at work.
Overall not too bad. For your next Klingon build or any model for that matter, consider preshading. It will add a little depth to your work. Adding highlights in the center of the panels will help break up the uniformity of the color. Maybe even a oil wash to bring out the small details on the kit. And I would also consider a final dry brushing to help the raised areas pop.
Here is a pic of my Vorcha completed a few years back.
