SPR-T3R Concepts I: Upper Body

Wooo I'm doing art again!

Some concepts for a fancharacter...in the Borderlands universe.
Did some art of this character before:
  

Some info that I'll probably add to later:
SPR-T3R

• Manufactured by Tediore
• SPR-T3R series robot was a short lived investment
• Designed as couriers of Tediore guns (company's philosophy that everyone needed an affordable gun)
• SPR-T3Rs are very, VERY fast runners, and can make quick, sharp turns
• No built-in weapons
• Cheap, lightweight, and very easy to manufacture BUT they cannot take a hit and fell apart very easily
• Poor longevity and invention of the Fast Travel  made them fall out of use
• Most 'died,' except for one...
