Hi,
It looks good, I'm going to make a suggestion though, the scratch built fuel tank is nice, however to get the rivets straighter, try using Tamiya Super Thin cement, you just brush some of the super thin cement in the general area of where the rivets with be attached, than quickly place down the rivets, the tamiya cement will allow you to move the rivet into the exact position you want it in, and than let it dry, than go over the rivet with another layer of Super thin cement for extra strength, don't worry about getting the cement on the surface of the part, as it's so thin it will not be noticeable after painting, also, if your going to do alot of rivets, to save time and get uniformity, try using Grandt line rivets, available from any Train shop, they are cheap, come in alot of sizes and type, and you get like 200 in a pack for about $2
I saw your posting on Missing-Lynx, I'm sorry about that guy who bashed your post, It's usually a very friendly group, and I'm surprised it happened, I hope you have better luck...
