First attempt at light reflection

I am not really happy with my first attempt at trying to capture a fiery reflection on these miniatures.  I read a few articles and tried a variety of attempts; mosly, I had to hurriedly remove with water almost the instant after application.  Nothing worked well for me. 

 

Finally, I just dry brushed with the same color used for the fire beetles eyes and glands.  The ass end looks okay; I like the reflections on the stone and back.  The front, where the eyes reflect off the legs and carapace however, are not to my satisfaction. 

Suggestions, tips or instruction sources are welcome!  

These miniatures are part of Otherworld's Labyrinth Lord boxed set:
