If you upload any of your tutor4u (or any tutorial) work to a webzone (deviantart, furaffinity, whatever) PLEASE credit the authors
Fucking HATE seeing on art sites when some faggot will upload the tutor4u cup or bear and post "I'm new to Blender, I just made this bear! =)"
No, no you didn't make it, you followed a cook book recipe and perfectly replicated someone else's creation.
Anyway, Zbrush is like blender's sculpt mode but imagine if a ton of people being paid real dollars were working on it to improve it, and it had a huge community making and selling improvements (brushes, textures, automated features), and so on; that's Zbrush
