In order to help us help you, it would be preferable to ask only one question at a time, with pictures as reference if possible.
Also, the question should not be too vague : "explain me how do you make relief on your maps"...
is very vague since there are plenty of ways to represent the relief on a map, as already mentioned.

Another example is when people ask general opinion on a map without asking feedback on a particular area.
They tend to either get very general feedback that are not necessarily helpful: this is a great first map!
or none at all, which is even less helpful but understandable if people don't have anything meaningful to say and nothing to comment on.
