For shoujo art style, I mostly like the cute but smooth and clean look. Whereas for shounen art style, I mostly like the edgy but expressive and neat look. I don't really like the overly frilly and glittery saccharine type of shoujo art, nor I like the overly angular and brutal type of shounen art.
For me, I mostly like CLAMP's art styles for series like Cardcaptor Sakura, Chobits (even though I don't really like Chobits), X, Magic Knights Rayearth, and Kobato. I am not really a big fan of its nowadays "noodle people" look, nor I am a fan of the angular art style on some of CLAMP's earlier works.
Pffft shounen is aimed more at boys isnt it X3 Where the girls are always flirty and the guys ooze manliness And then they kill stuff with awesomeness!!! XD
And I take it that Shoujo is aimed more at girls? It seems like a soft and fluffy story based on a girls romanticised dreams of meeting true love~ Daaawww :3
