There’s a green oak-tree by the shores Of the blue bay; on a gold chain, The cat, learned in the fable stories, Walks round the tree in ceaseless strain: Moves to the right – a song it groans, Moves to the left – it tells a tale. There’re marvels there: the wood-spite roams, Midst branches shines the mermaids’ tail; There are the strangest creatures’ traces On the mysterious paths and moors; There stands a hut on hen’s legs, hairless, Without windows and doors; ~ from "Ruslan and Lyudmila" by A. S. Pushkin
That's s project I did at the end of last semester, a fantasy tree in ink. It actually has nothing to do with the poem, but I thought it fit well I'll have to draw that oak someday, too...
