I've always preferred dynamic, emotional and quick sketches compared to drawing super detailed illustrations which take so many hours to create. However, the truth is that you should practice both.
After some time, it turned out that I made lots of these kinds of sketches. At the beginning subjects were different, but then I decided to focus on superheroes. I started from the ones which I liked the most, specifically the Hulk. I wanted to see how well I dealt with it.
Personally, I didn't want to select one particular style, instead testing different techniques - and because of this experimentation I feel that I am constantly learning all the time.
Finding your own style is a long process, some never find it. But the most important aspect of creation is the process. Those moments where you fail and those where you make your own conclusions.
Reward is not the most important, the hours of training and things you have to resign to in order to achieve your goal. It's a bit like training in a specific sport or learning new a language - the more you know, the easier it becomes to get to next level. Thanks to this you become "complete,” elastic and unpredictable ("Be like water my friend” - Bruce Lee) .
