Cardcaptor Sakura is my favorite Magical Girl series. Not only is it such a wonderful series to consume, it's also very easy to recommend to people of all ages, genders and taste in anime! I love all of the characters, Though I must say Yukito and Tomoyo are my personal favorite characters. I love Sakura as well and all of the characters. I much prefer he anime to the manga. The animation quality also stays consistantly good throughout the entire series!!
You can legally watch the series on AnimeLab if you live within New Zealand/Australia. Otherwise I'm unsure, propably check Crunchyroll.

Here are some official Cardcaptor Sakura arts I like!! They are from either the anime calendar, anime official promo art (such as magazines) or artwork by CLAMP themselves.
