Less is more. This statement is accurate in numerous aspects of life, sometimes including art. The hardest part in drawing (at least for me) is deciding when the work is done and doesn`t need futher improvments. Scribbling some lines can be easy but deciding that this is the end of your work can be tough. But after further looking it may seem that your work in this 'raw' condition is exactly what you were aiming for.
There are so many great illustrators out there whose style is so minimalist yet still catching: Garance Doré and David Downton are one of my favourites just to name a few.
