No, I still don't think you get it. Look at it more.  Your light just makes no sense.  At the point that it needs to be the lightest, you abruptly make the color darker.  On the other side you don't put in the reflected light, and the middle you left completely untouched which doesn't fit in at all and is actually just wrong. 
'Study'  means to look at references long and hard and make conclusions from them.  You clearly didn't actually learned anything from all the examples of ligh rays since you still only have a couple that I drew in for you.  It needs to be more consistent.  And I won't give more examples because I'm starting to feel like I'm bashing you than helping you. 

I think the dithering on the glass could be larger.. the dithering part should be around as large as the 'flat color' parts.. I think.

better!
the contrast between lightest glass color number 1 and number 2 is pretty large, and the one between number 2 and 3 very small.. maybe you could search for a better color between 1 and 3?? (pixel outlaw made great tool)

If you have allready recycled that color from somewhere else there isnt a big problem :)
You could try to change it a bit and see what happens, but if I would have made this I would not have done it (just cos im lazy) :) Btw you can make the dithering strokes on the outside (the water) some larger too, and maybe some more advanced :)
Now you can really see 3 stripes of different colors of water, but its maybe better if you cant see that any more :)

Do you have Graphics gale?
