how to put hieght and muscle on a figure

thanks man, ill try that!

For the added height I suggest cutting throught the in the thigh and maybe somewhere bellow the knee also and adding a slice of plastic or a dowel, then sculpting over it to match the wrest of the legs. For the extra muscle and bulk just try sculpting rock to match. This is pretty easy just use the rounded end of a paint brush or any cheap sculpting tool and make different sized indents like small craters, and then use a knife or some sharp tool to make the cracks inbetween each plate(take a look at my custom hanny for a example of this.
