Looking for feedback/suggestions on a "belly" prop.

[mrman225]

I had the itch to make something like this a while ago and finally put something together with stuff I had lying around.

It's fairly simple right now, just a backpack I took the "pack" off of and a throw blanket I sewed onto it.
It can hold about 30lbs right now, but I'd like to get that up to about 200. (BIG stretch, I know.)

It on the ground.

The front.

The side.

Me wearing it while it's empty.

And full.

Feel free to give suggestions on making it better.
