My weekend pic, for it's a rarity to see all shiny eeveelutions at once.

I actually like the colors all around, but the major headache was coming up with a background that isn't empty or boring. For each eeveelution I have a different opinion on the design:

Leafeon: At first I didn't notice much of a difference from the normal one, less natural colors, but it's alright nonetheless.

Glaceon: Brighter shades of blue all around, this one is probably my second favorite next to eevee.

Jolteon: Not a bad color choice, some people like this shade of green.

Vaporeon: The pink and purple colors make this one interesting, it's still beautiful nonetheless.

Eevee: Silvery and still mega cute, I really the choice for the color on this one! My favorite of all the shinies! ^_^

Flareon: Brighter colors make this more firey in my opinion, kinda like charmander.

Espeon: Not too wild about it's colors, I know a few people prefer this one over the original design.

Umbreon: My third favorite, I like the blue rings over the standard yellow, looks cool this way ^^
