UFP Penal and Rehabilitation Bureau Reimagined

I recently watched the TOS episodes "Dagger of the Mind and "Whom Gods Destroy" and I decided to reimagine the logo that was seen on the Penal Colony's Staffs Uniforms. So this what I came up with. I kept the open hand and the dove (redone) and I changed the globe on the top to reflect Brainwaves working in unison.

EDIT 12/02/2014: I have changed the design in the top globe to reflect a star meaning hope.
