A friend of mine and I are both artists and as we were both comparing our styles, she cited on how my art was a messy, sketch-like style, while her style was more clear and refined.

My other friends who also draw, have a more clean-and-clear approach. They also claim to have never successfully done sketches or anything like i do. Out of all of my friends, I have been drawing the longest and it has always felt natural for me to be sketchy artist.

Well, back to the main issue.
Is it just a personal trait or something that comes with skill and finesse? I feel as if the answer is right in front of me, but im still not sure..
