Here you go Ben.  This is an easy tool to use.  You can have the satisfaction of proving this yourself!!

Sorry I guess I should  have told all of you at I am only 15 years old and I don’t  have a computer that’s why I wanted some one else to simulate the circuit or for some one to tell me if the think at the circuit wud work

But you apparently have a web browser, so you can use this.

That schematic shows quite a bit of effort.

It looks to be master/slave flip flops, but it's not quite there, I don't think.
The set of one flip flop feeding the reset of the previous flip flop makes it seem like you were aiming for a "traveling bit" divide-by-four counter.
The cascaded ANDs makes it seem like you were aiming for a binary divide-by-sixteen counter.

I tried that web editor on a cell phone, that would drive me insane.

You can make master/slave flip flops out of NORs and ANDs.
Still, with NANDs being the cultural favorite, using just NANDs seems more recognizable to most people.
Here's a toggle flip flop using NANDs.
