Awesome Knex Crossbow

Here is my first instructable so I hope ya like it. I have been working on this for awhile and now I finally finished it! Please no bad criticism but I will accept nice criticism and ideas on how to make it better! :)

Put together 5 yellow connectors end to end and connect with green rods. Do this four times. Attach blue rods to the first set of yellow connectors as shown in pic 3. Put light blue rings on blue rods then attach a second yellow connector set next to blue rings. Now you need to make a stick using 5 orange connectors and green rods like in pic 4. Attach the orange stick to the blue rods through the orange connector holes. Then you add another yellow connector set next to the orange stick and blue rings and the last yellow sets it looks like the first pic.

Pic 2: make 2 of these.
Pic 3: add blue rods in these places.
Pic 4: attach like so.
Pic 5: attach these in the correct order.
Pic 6: do this on both sides.

Attach blue rods to the end of the track.
Then push blue rods through the holes in the orange connectors on the bow. Then attach grey and blue rings as shown. Add the end caps and your done with this step!

Pic: 1 make this.
Pic: 2 attach it here.
Your done!
