I like pre-renaissance western icons. They resemble eastern icons more but yet retain that typical western flavour:
That is a beautifully-executed painting, but it would not qualify as an Orthodox icon. It is almost photo-realistic, three-dimensional, with elements casting shadows, and using linear perspective, which roots it firmly in the earthly, temporal world.
Icons, with their flatness of composition, their elongation of bodily proportions, their inversion of linear perspective, their non-naturalistic abstracted portrayal, and absence of casting shadows, attempt to express what is not of this world - the timeless, the spiritually perfected, the heavenly.
