Puzzlerium Tour: LITS (Double)

 

 Rules: Shade in some cells such that each outlined area contains eight shaded cells that form two tetrominoes. No 2×2 square can be shaded completely. Tetrominoes within a region cannot touch through the edges. All shapes must be connected to form a single contiguous group of shaded cells. Identical figures, regardless of rotation or reflection, cannot share an edge.
