does 3d modelling just not like me?

ok going to attempt a full human figure this time......

and so far for me its going good.

but one little hitchup.


this is an image of what ive got so far here i virtual mirrored the other half of the body there.

now when im working i like to have a quick peek of my model in quick smoothed mode, just to help me see hows its looking, which helps me a lot....but once i mirrored the other side to my body and had a look at quick smooth mode this happened here

can you see where the middle join has been pinched........does anyone know of a way to sort that out now....rather than trying and maybe messing up my model later on ( which im proned to doing )

Simple prob with a simple answer: Delete the inside faces...i.e. the faces that are going down the side (where the spine is). Now mirror, it'll work fine.

thank a lot ill try that
