Inspirational Model Update - The Pinch Problem

As, now, I am pretty much finishing with the modelling process of my Inspirational Model, I am at the stage of doing final checks of the model, making sure the polys run smoothly and are creating what I actually want with this project.

Whilst I was checking the body of the model I noticed a strange 'pinching' effect towards the bottom, as illustrated in the screenshot below.

Not only does this not look appealing on the model but also I could affect the textures when I come to add them to the model, it could distort or stretch the textures; ruining the model.
I believe this is caused by the turbo smooth that I added to the model to create the smooth flowing polys.

To overcome this problem I began by deleting the 'Turbo smooth' modifier that was applied to the model. This instantly got rid of the pinch but the model now looked rough and low poly. I then tidied up the bottom part of the body by re- shaping the polys around that are. Once this had been taken care of I then went through the body section, applying smoothing groups to the surfaces, which created the same type of smoothness from the turbo smooth but didn't create that pinch effect at the bottom.

Below are images of the new and improved body of the Inspirational Model:

Inspirational Model Update - Low Poly Arm Model

The next step for my inspirational model was to model the arm.

The images coming up below are of the low poly version of my model.

Once the character has been blocked in I will go back through the model and add more edges, giving the model a smoother flow and look to it.
