when i see all these well done character models is it really done from just blender? because whenever I try to make a model using blender it turns out horrible do i just need to practice more? or is there some other tool people are using?

i know what you mean i dont know how people make such great models my geuss is it takes about a week (or more ) ofmakeing and tweaking the model and then makeing a really good texture for it

There probably aren't many modellers who will make any mesh completely from scratch. Most will import an existing one and adjust it, unless it's a basic shape. Characters would certainly be rework most of the time, as the human figure (even with the Elven, Argonian, and Khajiit variations on it) is well-established as a series of base meshes in various resolutions. Many of those were imported from digitised sculpture and live-model castings, so the meshes were modelled the old-fashioned way, not with digital tools.

It would not surprise me if many fantasy creature meshes aren't created by cut-and-paste from digital imports of real animals (and parts of people) and cleaned up afterward. After all, it's much easier to build a Unicorn by adding a horn to a horse model.

this is what i realized after some thinking

A lot of stuff is cut and paste pieces together, but simpler things like weapons are mostly custom built. Then there are also a lot of people who are actually good and can do their own custom stuff.

In addition to blender you can also use other programs to modify your mesh, normal map, or color map. Things like Milkshape can be used to great effect but are very expensive. There are also cheaper alternatives (z-brush or sculptris). But ultimately it takes real talent to create high-quality models and textures and you have to have lots of experience and love to get to that level, regardless of what programs you are using.
