It's a good basic to start from but you need to add more detail

I assume that you used some reference images thus qua form you need to tweak it some more.
Here's a tent that we use for our current project atm. The modeler who made it paid great attention to the shape just to indicate how important reference can be.
730 polys

But you're on the right track, just keep on modifying it
