You took on quite the "technology challenged" kit maker in this build. Think about making your tracks settle on the road wheels with some thread (use reference photos). Next thing I would do is make sure your vehicle looks as good as those reference photos, i.e., add some slight applications of dirt (that will help hide some of gaps where you glued some pieces). Also, consider using super glue during your build...especially when big pieces have to be held together. The super glue will actually add 'strength'. I also try and use the philosophy when building..."now, would this appear on the real vehicle?"...mentality, it really helps. Then if you can manage it, try and go look at some real tanks and trucks..take tons of pictures! Other than that, you've got a good start here!
