This was my first attempt at a space vehicle.  This particular Delta IV model can be found here.  This is a 1:200 Delta IV as flown on flight 301 in August 2003.  I did find that many of the cylindrical pieces didn't want to match up to each other.  I will chock this up to my lack of skill and to pushing myself to something new.  If I were to do a Delta IV again I would probably upscale this model or do something larger than 1:200.  My fat fingers find 1:200 to be a bit fiddly.  Overall it is a good representation of the Delta IV, but don't take my particular rendition as representative of the model.  The author's images look much better than mine.
