Thanks Luckmann! I've actually already done some work on tiles with the concept of using transparency for my new set. I think for regular tile transitions it makes my work more efficient when I can have a forest transition tile into transparency vs. doing a forest transition for snow, mountain, etc. I've also played around with some cool concepts for transparency, including shadows and fun landmark concepts. Also, I hear you on the snowy tree thing and I'll see what I can do!
