GustavoI'm not good at interpreting pics, but...
Who is that person behind Lisa (I'm confused with the proportions, they look female to me) - is that Maggie (hairstyle is very similar), or... you?

In the first case, I'm puzzled... Maggie admits Lisa in love, and Lisa neglects that and alienates her

no, both parts are impossible. If that's you, then... then I hope the story will continue in more bright way.

Technically the sketch is good, a bit overdone with symbols, but the scene is very dynamic, which is unusual for you - you tend to draw "static" situations more. Unusual move, and I like how it turned out. Sweet (although a bit sad) drawing, please keep it up.
