It looks really nice mate. All the colours wok together and unlike a lot of Eldar models it doesn't look like an explosion in a paint factory.
To be honest the 'glass' was quite cloudy and didn't look all that great so I probably would have done the same. One thing I might do though is paint the window frames that Yellow colour you have on the hull. As it stands the frame and window just blend into one.
Free hand is awesome too. Rep for you Sir.
