Technically the best place to start with a sculpture is from the feet up, while this is good practice I always beginning with faces, because they're hard, they make of break a model and I like doing it at the very start, mainly to get it out the way, but if things go well it also means I have a lot more enthusiasm for the remainder of the project. I begin with the feet and slowly work my way up, this is a skinned down layer system at the moment, getting the muscles right at the moment is what matters so a detail layer becomes all the more easy. Lower leg completed I then move up to the upper leg and the torso.

From here onwards I begin to lay down some more structure work.
I begin by adding in the costal cartilage of the rib cage, this is done as that side of the torso is stretched, especially with the raised are which means that you will see the bottom boarder and a series of lumps that look like smaller muscle but are in fact cartilage.
This will be added to both sides as it will help my balance the position of the rib cage, which in turn will help me with all the surrounding, connecting and supporting muscles, even the chest. A small note to add here, is I have made a mistake by making the protrusions of the cartilage far too thick, they would in actuality be much thinner than this.

From here I've provided you with another view to give you an idea of what I'm aiming for.

Next step(s) is to work on the abdominal layers, but I start on the outside with the internal obliques, these are responsible for pulling the torso up and to the side (as shown by arrows).

External obliques by contrast pull in the opposite direction.
I then add in the seratus anterior above and the points of the costal cartilage (I ending up blocking them out when I got carried away) I can highlight them if it helps?

I also add in the rectus abdominus, the six pack muscle and here I make a few changes.
The first is that the muscle itself usually comprises of four "six pack" muscles and two lower ones which don't have a split down the center of them and are much longer than the other four.
I also make sure that the ones on the left hand side of the body, bulge a little more with the supporting muscles (because of the rib cage tilt, they will be shortened in length, as will the supporting obliques on that side of the body).
I also take this opportunity to add in a touch of my own...
Saurus as standard come with natural thick armour, so it seems a bit silly to me for this vital area at the front to be exposed, so I pull a slight edge on each Rectus abdominus muscle to make it more thick, scale like and like natural armour where the muscles can slide over each other like inter locking plates (will smooth out the detail more once I have got the chest work completed)

As for the anatomy of with the arms, I had to start off by cutting away a good portion of the pec muscles and then sliding in the bicep. The next stage is to check the angle, the position of the bicep depends on the position of the hand holding the weapon, as everything changes. Once that was sorted I added in the supporting muscles, heads of tricep and then the elbow joint and epicondyles. I then add in the anconeus (triangular muscle which the other forearm flexor muscles tuck in to) as well as the brachioradialis as it would be very prominent in this position.
