Genre Spotlight 68: Oasis (Puzzles 394 and 395)

Today's genre is Oasis, a neat shading type invented by Matej Uher for WPC 2016.  I've been long scared of this type and never really attempted it.  I'm glad I gave it a go, it's much more reasonable than anticipated!  Still not easy, though....

Rules: Shade some cells so that no two shaded cells are orthogonally adjacent and the remaining unshaded cells form one orthogonally connected area. No 2x2 area may be entirely unshaded. Cells with circles cannot be shaded. A number in a circle indicates how many other circles it could reach by traveling only through empty, unshaded cells.

          

As usual, two puzzles.  The first one is maybe a bit harder compared to my usual first puzzles, because the ruleset definitely takes some time to get used to.

The second puzzle is big.  It originally was not intended to be big, but I kept needing more room to make the intended setup breathe.
