fred tend to use the PolyTools set for creating his stuff, and those good reference pictures were just simple sketchs he made

he's good simply because he loves what he does, it's taken him around 3years to get to the level he's at now ... seen him improve alot over those years, most of which just comming from practise rather than anything else.
but in the grand scheme freds just an adverage modeler - there's one right now that i'm keeping my eye close to called Caronline Delen, who is a truely awesome modeler - there's a few things i'd love to teach her when we both finally have the time about mesh development and some things i'd love her to teach me about texture development.
but she has this cute lil character called Lena

which is just such awesome work.
personally i can't wait until fred get into Softimage and Maya properly - cause i think when he learns that they have the polygon tools which allow some truely amazing things to be created quickly and easily he'll love the possible detail and editing level it has in it.
i'd love to see Max get similar polygon tools to Maya, especially the Vertex Cleanup and automatic crossinsert
ya know how many people say "man i wish i could model like that!" and the funny thing is that it isn't any real special skill involved in modeling or artwork - its just a case of loosing yourself in the development, you start simple and build from it and you'll find that it all falls into place quite nicely.
