Character and POV

Frustrations abound in my latest story for the workshop that I'm distributing tonight. The main character who goes through the transformation of the story isn't the POV character. The main character doesn't seem to offer enough for the story to be told from his point of view. He also experiences a trauma that changes him completely. Maybe I'm just wimping out by telling the story from the point of view of a second person, who doesn't really go through any change whatsoever.
The core idea of this story was ripped form an earlier story that I don't think I'll keep. The main characters show up in this new version, but they could be cut. I don't think they add much to the story. They could go back to their own tale, but their story would have to have a difference propulsion method. (In the original story, they worked around the death of the main character in this latest story. IN this story, the main character doesn't die.)
What this probably means is that this story isn't ready to be told, or I need to water it a bit. I did water it several times, but I may not have pruned wisely. It's up to 2,900 words, which isn't long by my real standard, but it makes me think twice before copying it 19 times for the workshop.
I guess I haven't really braved inside the MC's head enough to tell the story from his POV. I don't mean that I want to write it in first person. I just tend to show what happened off camera, summarizing the information, or showing the results of a series of activities instead of showing them. Perhaps if I did that it would make more sense.
