Were I asked this kind of question, I'd say something like:
I like to find beauty and interest in the very mundane, things that are overlooked by others.
This definition applies to much of my landscape work and all of my industrial projects. Oh, sure, I'll photograph a great scene when the opportunity rises.
So, do you know what makes you light up? Don't just say landscape, what is it about the landscape that interests you - is it the light or the majesty, the small details, the off the beaten track, the downright inaccessable. When photographing people, is it their expressions or interesting faces?
Which is more important to you, composition or light?
Being able to describe what moves you in detail will help you in your search for future images.
