The silver crown of Nargothrond

First part of my closing project in art lessons.
Scene from Silmarillion, in which Finrod is going to leave Nargothrond... and then die

Technique: tempera and watercolours. Details here.
(The strange stuff above is - a window. Yes, it doesn't sound very possible, but there were windows also in Moria and I think Nargothrond isn't supposed to uglier - anyway it was also built by dwarfs )
