I've been thinking of doing something like this wayyy before they came out with the Storm rules, always thought it'd be sweet if a landspeeder rolled around and WHOOPS, you just dropped off some scouts.
Great conversion overall. The passenger compartment seems a tad bland, but I guess you were going for the ability to actually put your scouts inside the vehicle, so it's all good. Question though: what did you use for the diamond plating? Always wanted to get that effect going on my vehicles, but I could never find any material small enough to fit. :[
