Ok guys. i think that i am freaking out. Learning Zbrush like a maniac, but i still don’t get anything. I see people can do awesome and really stunning work from Zbrush. I don’t know how to sculpt realistic characters, with awesome details, like, wounds, scales, scars something like that.
Is there any good tutorials out there, to learn better Zbrush, and make awesome character like you guys.
it sounds like you need to study anatomy more than Zbrush.
Zbrush is just another tool in the artist’s belt.
Without a solid foundation in art having the tools isn’t going to much if you don’t know which tool to use when.
Basically, you can build a house with a saw, a hammer and some nails, but you’re probably not going to enjoy using the hammer to cut the wood and the saw to beat the nails in.
Hope that helps.
How can i learn better anatomy, so i can be able to sculpt in Zbrush?
Here are some links to video tutorials I found useful.

It’s just practice, but once you get the fundamentals down it’s really awesome! 
Well, i know is just practice, but i don’t know how to learn anatomy? Should i draw first then sculpt?
Step one is to learn the fundamentals of 3d. This includes theory behind stuff like triangles and quads, normals, box modeling, symmetry, textures, lighting, rendering, as well as common problems you can encounter like non-manifold geometry, holes, flipped polygons, unwelded vertices, etc.
Step two is to learn the program you want to use. There are tons of books, magazines, and videos out there so you’ll have to Google for them (Youtube is a good source too). Read the online manual as well as the PDF material included with ZBrush, then read them again. You can hold down the control key while hovering over an option in ZBrush and it will give you a description of what that feature does. Don’t be afraid to experiment! Good tip: save often and incrementally.
Step three is to learn the fundamentals of art. People interested in doing this professional usually go to colleges/universities to learn this stuff. It is possible to learn it on your own though. In your case you want to study anatomy closely and practice, practice, practice! Study the work of other artists you like and also pay close attention to people in regular everyday life, especially shapes and placement of features. No two are exactly alike. Learn to visualize everything in the world as a wireframe. If you can’t draw and/or sculpt with clay, odds are you won’t do well with 3d which is far more technical.
Step four is the most important. Doodle! It doesn’t matter what you doodle so long as you play with everything in ZBrush until you grasp what it does. Sometimes great art can come from what started as a doodle. Modeling non-organic things tends to be easier than organic (proportion isn’t as important and most stuff tends to be very geometrical) so you may want to start there. Again you need to practice, practice, practice! The more you do, the better you get. It doesn’t have to be good right now when you just starting out, so don’t get discouraged if you end up with a lumpy mess. Remember, every mistake is an opportunity to learn.
a very helpful thing is google; it´s a search engine where you type in your question, and you will find loads of forums, groups, books, discussions about exactly what you´re out for
I have been learning anatomy lately. I don’t claim to be a pro, yet. What I have found helped a lot was learning the basic muscle lines. Try drawing a comic book character freehand that has a lot of muscles. Look for lines that stand out. An examples would be the collar bone (while not a muscle), it will be in almost every character with a neck and chest. I have found that there are “landmark lines” for arms, back muscles, etc…Hope this helps!
Eric Keller’s book “Introducing ZBrush 4” helped me get through ZBrush’s learning curve. If you have the basics down and just want help getting though the interface and terminology, I hope that will help you as much as it did me.
If you have the gist of ZBrush but you want better results, then the other posters are probably right, focus on anatomy and getting the basic body landmarks and scale correct.
