Also, nowhere do you mention to weld the two halves together. At which point would you have done that? Thanks.
As a rule not until you’re 99,9% done;) You should always keep it two halves as long as possible, since that enables you to model just one side=saving time, not to mention sanity;) Some (good) modelers then weld the two halves together and make subtle imperfections between sides, so as to make it more realistic (since one side of the face is always different from the other. Have a look in the mirror:) Also, if you’re serious about getting things exactly right, make sure you have some reference photos of the head from extreme angles and compare that to your 3d model. My heads never look right in 3/4 view after initial reference modeling:/
On a sidenote, the revised tutorial will have to be put on a hold, since I can’t decide on the best way to model. I’m a perfectionist, so I’m looking for a workflow that it’s both efficient as well as accurate. I usually scrap 75% of my models halfway and start over:/
edit: Which is why you never see my work at Elysiun;)
