NICE DUDE! Lovin it.
It is alot of fun isnt it!? Make sure you take your time and dont get too excited I have learned over the years to make sure to give the task it due time. Dont rush it and you will be happy later on when your results are perfection.
And always ask us for help!
Here is a tip, remember... LATEX SHRINKS so make your sculpt larger than your actually body. Do not make it Exactly your dimensions, cuz when you cast it in your mold the casting will shrink down and be too small. Its the natural process of latex drying in a stone mold.
goodluck, keep us posted.
