Feanor

I can't understand why Noldor elves are been illustrated as skinny really can't, especially in Finwe's house. Do you actually know anything about Tolkien's lore???

“…and they were tall and dark-haired and strong like fir-trees, and from them most of the Noldor later were sprung.”
“…The Noldor, outnumbered and taken at unawares, were yet swiftly victorious; for the light of Aman was not yet dimmed in their eyes, and they were strong and swift, and deadly in anger, and their swords were long and terrible."
"In general the Sindar appear to have very closely resembled the Exiles, being dark-haired, strong and tall, but lithe."
"The Númenóreans ... are in constant communication with their ancient friends and allies, either in the bliss of Eressea, or in the kingdom of Gilgalad on the shores of Middle-earth. They became thus in appearance and even in powers of mind, hardly distinguishable from the Elves..." –So how are they stronger than the Eldar although they are so similar that was hard to differentiate one from another?
'' But in the dim dusk of a winter's day there appeared suddenly among them a man, as it seemed, of great bulk and girth, cloaked and hooded in white...'' - This is a physical description of Beleg in comparison to the men that were following Túrin Turambar. Keep in mind that he’s one of the Sindar the Noldor were in general larger - 'Teleri were in general somewhat less in build and stature than the Noldor.'
