There are two concerns I'd have with that weapon.
One, PVC core polearms tend to be whippy at anything above minimum length. Keep that in mind. Unless you're planning on gripping it by the haft, that setup doesn't look like it has nearly enough grip room to safely use it two handed. Part of how you can control whip in play is by having a polearm grip that goes up past the midline of the weapon so you can choke up on it.
Two, your thrusting tip seems over-long. How far up it does the actual pipe foam come? From the second picture, I'd be concerned with it folding over on a thrust and possibly tearing off, which is a safety concern.
The head isn't what I'd use, but whatever works for your character is what you should go with. You'll likely need to rebuild it fairly often, though. Small points like that are going to compress out the foam over time with strikes and the tape will stick to itself, making the points uglier and uglier over time. Accidentally letting anything lie on it while transporting/storing it will make that process worse.
