Help me please...

Hello guys....l need your help....I've been doing the mc skin editor for 3 days .... I wanted to get your opinions on this subject... (since most of you are experienced) well...I want to know if the shading of hair and or skin and etc. places is limited (apparently) so can I find and do it creatively as I want or are these shading jobs 3-4 processes? because I looked at shading on youtubed about hair and I came across either 1 shading process or 4 or something. ...I know it's a stupid question but I wanted to ask anyway because I need it very much, I want to create it myself but I can't do it, but I don't know if I'm new or what, I don't know...., please write what someone who is new to these issues should do and why should I start...for example, I want to do 3D or something, do you think it's too fast... I don't know, please inform someone with experience or whatever, please write...whatever you know, write it all) Luv you all<3
