Its really hard. 1 tree, a couple of seeds, no animals, island is insanely small, 1 hole about 4 blocks deep.
Seed is: ExoticGenesis
Seriously, that's the seed!
Just tried this seed myself and ended up on a bigger island than said one that OP mentions. Still not a bad seed overall since I could see some tiny islands across the ocean.
