Koi fish are one my favorite things to draw. Following are the steps that I use to draw a Koi.
Provide pen and a paper . Use a black ink pen to look like Japanese SUMIE.
On the paper draw the outline of the KOI.
Draw an eye on the side of your KOI.
Draw two wiskers on both sides of the KOI 's face.
Draw a gill between KOI's face and a body.
Draw a tail fin.
You are done! Add anything if you want to.
