Ok....it's quite hard to pick points with the ref image over on page 1 of the thread.....have to keep clicking back and forth to see. The first thing that I thought I found....and it didnt jump out at me - had too look for it....might be an annoying thing to fix....but from the look of the ref image on page 1, the chest/torso area is a little wider? It seems to be more chunky width wise...I've put a red arrow where I mean....

Edit: or is it? I think that the bumblebee in the first post of this thread has more of a 'chunkyness' to it, which I would aim for in modeling what remains to be modeled...??
