Straight from her first appearance in Batman Beyond, We can tell this character has Rule 34 potential. Pink hair atop brown skin, Nice African lips, ample chest, unique apparel, And the hourglass shape best seen by Bruce Tim.
Your fan art totally lives up to what I just said. The soft smile and office uniform show's she's ready to star in a porno. The white collard shirt is supposed to work best with the studio lighting and better contrast her skin color. Her body position and hand gesture shows She is either really exited or does not know what to do first for today's job? Either way, Love your work.

Though I will critizise how her hair and skin could be a little darker. Matching the exact shade and tone of how she looks in the animated show. But I can understand this is how you make art. Still looks great!
