Hello!

Virtual and abstract realism are both concerned with A bold, free style that's on the brink of caricature. 

These art styles are the fusion of abstract and realistic art. It is difficult to explain because these are styles are completely opposite, but virtual and abstract realism manages to create a synergy between those styles. The best way to explain this art style is by saying that it tries to convey the emotions behind a real-life object, and it is usually done through a caricature style.

Have a nice day!
