I am sorry, but this puzzle still has multiple solutions (see hidden comment again)

The old puzzle had multiple solutions, this one should only have one

As far as I understand the rules, the two large regions have to be divided into L-shaped parts, for which then the normal rules apply.
Unfortunately, in my opinion this leads to multiple solutions (I found at least two that are not the intended solution, see hidden comment) as there are quite a few ways to divide those regions.

I really like the general new concept and the first two puzzles. But here I don't understand the special contraint. Where do the L-shapes appear? As shaded cells in a region? as unshaded cells in a region? Are there - against the general rules - more than one shaded group? The examples seem to me as showing rather the general rules, not the special L-part.
dogpond12: The L-shapes are the regions, not purely shaded or unshaded, something I should've explained more in the rules.
