Sharp claws, and huge intimidating wings.

This character is pretty bad ass.

Ratsmith:
Scarlet is not a real villain, but like Shadow, she has no real intention to anyone. She helps where she things she has to help. Otherwise, Scarlet goes her own way.

Runhurd:
Well, I'm not sure what cup size Rouge has, but Scarlet has D Cups with a body size of about 180 cm (after all she belongs to the Eden Crusaders and not the Sonic universe)

You did a pretty good drawing, but her ears are a bit too big and her fangs are not leaving her mouth.
Oh, maybe one thing... could you please give her a different pose? This one looks kinda... weird ^^;

I did not mean to imply anything about the nature of this character. I was only commenting on her visual look which does impress me and meant no slight to her alliances, temperament or level of good and evil what-so-ever.

Please accept my humble apology for offending you, if you were offended in any way.

Nah, it's okay :)

very neat
