The whole thing is colored in now. At this point, all it needs is shading, and maybe a background that isn't pure white.

This is one of the various incarnations of Crisis that exists, all subconsciously linked between dimensions. This allows every Crisis to recognize whatever interdimensional travelers her other incarnations have met. All Crises tend to follow the same basic template, varying in age, gender, species, etc. Common physical traits include green eyes and excessively-long, black hair. Common personality traits include an dark, mysterious facade over an eccentric foundation and a love of terrible puns. Typically prefers black and purple clothes, including wide-brimmed hats and flowing cloaks and ponchos. Combat skills involve dual-wielding swords or guns (preferably both) and projectile-spam, although her most powerful attacks have included the formation of black holes. Usually straight, tends to be asexual.

This particular version of Crisis was used in a Sonic the Hedgehog RP (obviously), where she was a wealthy heiress that constantly seeking adventure. She utilized a form of paper magic specializing in money, although she could magically "Burn" the money as a sacrifice to temporarily summon weapons and other items. I haven't played this character in a while, though, and the current (non-Sonic) version I'm using is more giant-robot based.

A number of official Sonic characters were referenced to make this image. Blaze the Cat (created by Sonic Team, first appearing in Sonic Rush) for the front pose, Tiara Boobowski (created by Christian Senn for an unreleased game), and Antoine D'Coolette (created by Rafa Knight and Ian Flynn for SatAM and the Archie Comics series). Any similarities to another artist's image is purely coincidental
