Thank you for posting your comment! I can see the jaginnes and the scribbled lines. Based on this information I will try to improve the quality of the next work.

It definitely reads as a whale.

The pixelling here feels very uncontrolled, like you just scribbled in the lines and colours and didn't take the time to refine them. There are some jaggies in the lines and a lot of the colouring is very noisy.

Thank you for the feedback! Here is the reference www.google.lv/url

Edit: My flash is not updated, so I cannot view the image reference.I googled "whale" .It was the fourth picture from the left side.

Yepp, that's clearly a whale. If possible, you should always include a link to the reference picture if you used one.
