Many thanks! 
I guess one of the parts I really enjoy is creating immersive / atmospheric environments and stories. So any part where a player walks into an environment and is captivated or just enjoying the surroundings – this is something I enjoy and find rewarding to see.
A bit like being a kid (or adult!) and walking in a forest and for the first time finding an old deserted house to explore, or a hidden waterfall etc… Creating that feeling of mystery/excitement/fear is something I am looking to create.
