Thar and Risha - concept

I wasn't suppose to draw anything until the semester was over, but... I CAN'T D'X...! I just needed to draw something to chill for a while... and I've been thinking for a loooooong time on adding Thar and Risha to the SGPA haha (specially Risha, lol)

Risha is a crazy and violent woman who enjoys traveling without a clear goal in mind and make fun of the people who fall for her flirtatious personality. Thar is a mysterious man who lives to fulfill a secret mission. I'm really debating myself if I should add Thar to the group... and if I should leave their canon stories or create an alternative story for them... I'll probably end leaving their stories as they are lol. I really dunno They'll probably end being joke characters, since they're way too powerful.. 

I'll add more about them when I upload their profiles, which I hope will be soon >_>...
