Polygon's Guide is pretty good.
Now having made a perfect one in NH, it seems the lower ball has to be about the height of your eyes - and the smaller top ball needs to be about up to your neck. I'll post a picture later as an edit.
Oh my gosh I want that ice bar.
This helped me get one perfect snowman but I just haven't been able to do it again which is frustrating. I wonder if different eye types don't align quite right.
