Character modeling (the torso)

Here is the torso modeling part of my model. Using the separate tool and the merge vertex tool to stitch the limbs together. The neck and main torso was created by simply extruding down from the neck, using 'G' to repeat the previous extrude made my workflow faster. The arms are polygonal cylinders, I mirrored everything once i created it on one side of the model (arms, hands). Using the edge loop select tool to refine the contours of the arms, and tweaking with edge/vertex selection.
