Name a few of the best skins riot has done

Arcade skins. All of them.

Dragonslayer Pantheon. Wings and no pizza feet.

Lolipoppy...... IM KIDDING IM KIDDING!!!

Zombie brand. Best skin in the game.

Definitely Not Udyr and DJ Sona for me

Super Galaxy Rumble. Hands down best skin. Otherwise, Spirit Fire Brand and Commando Jarvan are a close second/third

Urfrider Corki is my all time favorite.

Snowmerdinger!

Warden Nautilus. It just looks completely badass.

I really like Silent Night Sona and most other pretty or elegant skins for female champions (I'm a simple man). Gentleman Cho'Gath and Giant Enemy Crabgot are close runners-up.

Mecha Malphite is a gorgeous skin.

Armor of the Fifth Age Taric

Surprise Party Amumu, Dino Gnar, Superb Villain Veigar

Officer Vi, Popstar Ahri and the Heartseeker line are among my favourites.

Dj Sona and the Project skins are impressive.

Ravenborn definitely :P

Corporate Mundo has a great voiceover. Zombie brand has amazing animations, especially the walking one. Star Guardian Lux has well done particles.

Gentleman Gnar, Winter Wonder Lulu and Omega Squad Teemo are all personal favourite skins of mine. Lovely splashes and even more amazing game models and animations. Very well made Riot!

Primetime Draven

Aether Wing Kayle - Best Recall and crit anim in the game. Spirit Guard Udyr - BJ Sona can fuck right off. Project Fiora - Creepy faced Fiora with an even bigger booty. All of Leona's skins minus Iron Solari. Frostblade and Order of the Lotus Irelia.
