just remember that in miniature painting you often cheat. you often paint light where there shouldn't be any, you exaggerate contrasts, and change reflections from NMM: you may not remember the discussion when a few painters thought that the next step in NMM after SE-NMM will be NMM reflecting the surroundings, especially the base and parts of the miniature. somehow it didn't work. And SE NMM always looks unrealistic and fake. Why? If you have your mini in a cabinet - the sky and the ground should be in the color of your cabinet. If you have it on the table in your room, the ground should be colored like the table, and the sky in the color of the room. But your miniature doesn't change all the time, so it always (or most of he time) looks wrong.
As for the shadows and lights on the eldar. I told you mine were not perfect, but where I was going to was that the legs are generally tubes, like pipes or exhaust pipes. And on these the reflection is usually stretched lengthways, see:

you see what I mean - and as I said, mine was not good enough for sure, but it was just a quick painting in photoshop. just to give you some food for thought...
