Correct Tiger's Eyes using Pastel Pencils

Paul has sent me his Tiger Cub in progress painting and has asked for feedback.As a whole this painting is progressing very well but attention should be given to the eye on the right. Compare Pauls eye above with the one on the original painting You will see that the shapes is wrong and triangle shaped rather than the rounder shape on the original.Paul also commented:

How do i fix the eye? Some of the colours don't look vibrant enough, a bit muddy so to speak!

The best way is to carefully erase eye colours and then reapply them following the reference picture. The muddiness can be lightened using a putty eraser to dab off the offending colours before reapplying them.
