Ok, here it comes.
Bloodmoon Camille
The skin line is based alot on japanese ghost stories and folklore. With that in mind, I would design the skin around the concept of the Kuchisake-Onna. She would wear classic japanese clothes, wear a wide mask with a slit wide open mouth and her legs would be either one half of a scissor.
Passive:
AD: blood
AP: swirling ghosts
Q: Her scissor legs start glowing red.
W: new indicator with japanese looking ornaments in red
E: chains with kunai at the ends
R: arena is red, enemy is tethered with 3 chains to it
Chemtech Sejuani
Instead of her boar, Sejuani is riding a chemtech driven motorcycle. Her flail has a flask filled with a green liquid at it's end. Her clothes are oriented at punk style, classic Zaunite streetwear.
Passive: tubes on the motorcycle glow green when passive is up
Q: Sejuani does a wheelie and crushes into the enemy
W: new indicator in green
E: enemy is covered with green goo, the stacks are stacking up to a testing tube
R: enemy covered in green goo, the AoE effect is green liquid spread over the floor
Ironside Urgot
The general design, just like Malphite's in that skin line, resembles a pirate ship. He could wear a eye patch and a pirate coat. When Urgot is dancing, instead of a top hat he pulls out a pirate hat. His left hand is a hook, his right hand a cannon.
Passive: his shotgunknees are cannons
Q: a cannonball that is cracking and exploding
W: his shield has water animation and he yells "ARRRRRRRRR"
E: dashes and grabs the enemy with his hook
R: the drill is replaced with an anchor, he opens his stomach and there is a shark hidden in there.
Starguardian Vi
I want to see Vi as a member of the next Starguardian team. Her outfit should be a bit more boyish than the other Starguardians, her 2 familiars are transforming into her gauntlets.
Passive: starlight as her shield
Q: nothing special, simple dash
W: when she gets all 3 stacks, there will be a cracking star instead of a broken shield
E: sparkles behind the enemy hit
R: Starguardian flight, dashing to the enemy and knocking him up
Poolparty Jinx
Jinx got teasered in the Poolparty splasharts a long time ago, it's time for her to get that skin. She would wear a bikini (no big change to her current outfit), her guns are oviously replaced with water guns.
Passive: water is splashing around while she is running
Q: minigun shoots water, fishbones is a waterballoonlauncher
W: one strong stream of water from a waterpistol
E: piranhas (nuff said)
R: a big toy rocket propelled by a stream of water
Maybe to be continued.
