A couple suggestions:
1. Make sure you take pictures of the trucks from ALL the angles (ie, from the top and underneath) - also, do the cars roll, or are the wheels decorational?
2. Tags.
http://www.etsy.com/listing/113309249/wooden-pickup-truck - the title says it's a truck, but the tag doesn't mention trucks at all! (although it does jeeps) - make sure you diversify your tags as well or someone looking for exactly that product might not find it! Examples for potential tags would be: Truck, Car, toy truck, toy car, wood truck, wood car, boys,
3. Shipping. Trust me, I know how expensive shipping is, but I live in Canada, and if I wanted to be able to buy a wooden truck it would have to be from someone else. Even if the shipping cost to another country seems high, still have it as an option because I'm sure it would be worth the cost for the right buyer!
But so far great job, those toys look fantastic!
