This is my first go at making a anatomicly correct male human body but am at the moment going without reference other than my own body.

this is a very very good model…the only thing that just jumps out at me that needs some fixing are his feet…you did a dang good job with this model so far though, just tweak those tootsies just a wee bit more. Keep us posted.

you’re a pretty big dude if you using yourself as reference 
lol not quite that big yet but working on it pity I cant use a inflate tool on my body hey!
Here was a quick experement puting the model on a picture back drop with lighting. Iv got alot more to do on the model but when finished will make a female.
looks better, the lighting is wrong tho. it seems that the sun is on the other side of the ocean.
