I really enjoyed solving this puzzle myself and I hope you do too! As always, I struggle to estimate difficulty and I would think this is around 2-4. Please let me know!

Normal sudoku rules apply. Small arrows pointing out of a gray cell indicate the cell is larger than the pointed-to cells. Small arrows into a cell indicate the cell is smaller than the pointed-from cells. (Gray squares only interact with non gray squares.) Black dots indicate a ratio of 2:1; not all dots are given.
