The whole 3D and CG business is about Illusion guys/gals That's what makes this an art form, I don't care who you are or how good you are as an artist, you will always look back on your work and pull a HOMER moment where you go DOH! I shoulda done that or changed that, So post work is like death and taxes, it's something you have to deal with in a production world/environment to make a living doin this sorta thing. Nothing is ever perfect, nothing is ever right, it's just a limit in the biz you have to live with heheh.

Do atleast one thing a day that scares the hell outta ya!!
