ZBrushCentral

New here and to zbrush and need some help please!

Hey everyone,
First off some of the work on here are just amazing and very inspiring.
With that said I am new to digi sculpting and zbrush and would like to be half as good as some of the work show on here.

Now the question part:
Is there anyway to get higher details without retopology?
I am to the max with my subdivision (7 sub) but the sculpt need smoother cleaner details but can’t go any higher with the subdivision.
Any help would be awesome and if some of you good folk can point me to a good tutorial on anything relating to retopology that would kick a$$.

Thx ahead for your help,
Billy
