The Body 3



Extrude the last vertical row, 3 times, to make the back of the torso.



In Front view, Select the lower row of vertices, and extrude 3 or 4 times to follow the pelvic roundness. Feel free to change this in order to fit your model.
My low poly characters counts more or less 1250 vertices. If you need much less, you must limit the row extusions.



After some extrusions ( two or three) it's better to check, in Top view, the shape progression, to keep the control of your object.
Select, in Front view, an horizontal row of vertices, the one you want to control, and press, Shift-H keys, this will hide all the other non selected vertices, so, now, you can easily adjust the shape, in Top view.



In Side view, Select and Extrude down like in the image.
One way to keep the control of your modelling, is to keep the horinzontal guidelines more or less aligned.



Again, with Open Gl and trackball action you can work like a sculptor. The advantage of low-poly modelling is that it's quite easy to control the overall shape.
