Alot of job descriptions list that they are looking for "experts", which if you know anything about 3D, is alot to ask for.
It seems like in order to get any job in 3D you have to be comfortable with calling yourself an expert. Even jobs with intermediate or average pay sometimes list experts or "superstars" for 22-40 an hour.
Here is my Demo Reel
I like to call myself a 3D Generalist, that's expert enough to get most jobs done. If I don't know the answer to something, I will look it up online until I do.
