As has been mentioned it doesn't look to be hooked correctly.
Also normally what appears to be on the outside of the tire which is just hooked,
is usually on the inside and the "cam" over fastener is on the outside of the tire.
You connection points need to be the same length over all.
Where you have two links for your hook, you should have two links for the cam over tightener.
If the side chains are not even lengths your chains will have a tendency to try and walk off.
A bungee or two one the outside can help and shouldn't hurt.
I don't use any on my chains.
