User blog:Darkest Shadow/...Design Ideas?

Hi.... I was wondering if you guys had any ideas of designs for 3 new characters that I'm making.

Tempest the Hedgehog- Dark grey hedgehog.

Emerald the Hedgehog- Green hedgehog.

Storm the Hedgehog- Grey hedgehog.

So contribute by commenting ideas for certain characteristics like spikes, attire, eye color... etc. etc.
