Pengoral Archipelago

[BuddhaTheGreat]

Thought I'd try an island map, so here it is! The Pengoral archipelago is an island chain with a combination of volcanic and reef islands that may or may not exist in the same world as Eoruthan, beyond the Distortion Wall.

What software do you use for this?
I like the sea colors.
As I understand the matter, reef islands are used to getting sand beaches, so maybe some coastlines would look much smoother? At the moment the coasts seem to have a rather similar amount of 'ruggyness'.
Some island shapes remind me of Indonesia, is that a source of inspiration or pure coincidence?
