Yes, I remember this one time when I was really young (I've been drawing since I was 5) and I worked really hard on this one picture. But, then, after I finished it, I saw that everything was wrong with it and I started crying because I am a perfectionist and I was so mad that I had to erase or even redo my work. Ah...those were the best days.
But, yeah, I really like your drawings. The "Shut Up" one looks like One Piece.
Is that the style you tend to draw?
