dont do styles, start with semi realism or intense realism if you really like it, starting with a different style generally never works because you can almost never improve because you have nothing to improve on
When you start with realism your able to change things and your better able to change things without it looking like crap
otherwise, your stuck with one style, the one that you copied from someone else
so really just get a sense of realism before drawing and anime cartoon etc crap
