i primarily write fantasy, but also some scifi. i like places where i can break the rules to explore more freely. fantasy more than scifi because it has less constraints to me - scifi has this element of 'what will the future be like' for me that can often hold me back from launching ahead into the ridiculous, whereas fantasy can mean full freedom. also, i really like the earthy palettes and scottish-y landscapes, and i love mythology.
that all said for high fantasy, i love a bit of magical realism and low fantasy too. things like being human and harry potter, where reality and fantasy are integrated, really get my cogs whirring. and magical realism where the reality of things is ambiguous, like pans labyrinth, excite a whole different part of my imagination.
