Frustrated chef, frustrated singer, etc. etc. This what we say when we want to have that skill or talent but not able to achieve it.
As for me, I am a frustrated artist or painter. I love to draw even when I was in elementary up until I graduated from a trade school.
I love to draw nature, animals, even a human portrait. But it seems that I'm not satisfied because unlike other artist, they can do as if it was photographed, alive and full of colors.
I appreciate art, but sadly I have color blindness that could be one of the reasons I can't draw well or put colors on every of my drawings.
Below are some of my works.
