All I really care about, graphics-wise, is that the game is pleasing to look at. SS is a nice blend of the WW and TP styles, though I do admit that I preferred the TP graphics. However, I would call them 'less stylized' than 'realistic.' Sure, it had the most realistic graphics of the Zelda games, but it still had its cartoonish elements (especially in the characters' faces).
When it comes to SS's graphical style, I find it unique. It looks like the character models are going more of TP's style while the enemies are more WW. The background seems to be its own thing and it has really grown on me. It's colorful and really nice to look at. I also really like that Nintendo is using the cel-shading technique from WW. That just makes everything move much more smoothly and the lines are much less polygonal. As much as I loved TP's art, it still had that polygonal effect and I'm glad they're fixing it for SS.
