I would like to apologize ahead of time If things don't make a lot of sense from this point on haha. I am trying to make sense of the 30 pictures I've taken so far. The way I work is not really focused, I skip around alot ....ALOT . I don't stay on one spot too long that way the whole sculpt has around the same amount of detail.
A good turnaround drawing comes in really handy when blocking out a sculpt. To make sure the proportions of the character are spot on. I like to lay the sculpt directly on top of the drawing. You can also use calipers or a ruler.
Another good thing to do is to take a straight edge and draw a line down the middle of the sculpt. I do this repeatedly when blocking. Its good to know which way things are facing before you have details to show you.
I have seen too many sculpts with all these beautifully sculpted muscles with soo much detail and pores ,veins ...ect BUT they are ruined because they are slightly out of proportion.
The only way to fix that is to start over. So the best advice I can give you is to check, double check, and triple check that everything is in the right place before you even begin sculpting any kind of detail.
