The Colors of my life

First of all, I love this work.
I love your choice of colour, I love your technique with watercoulrs. All the shapes are beautiful and elegant.
The white background suits well the concept and the eyes are very expressive and make you stare at them for a long while.

But I did spot few mistakes that seem to appear in few of your portrait works.
The lower part of the face: mouth and nose appear slightly bigger than the eyes compared to standard human facial proportions. And the eyes appear slightly lower than they should be on a proportional face - creating a feeling of a nose to be just a bit shorter than it should be.

Also the left eye appears just a bit smaller than the right one, while the size of eyes in a healthy human usually resembles. And since this man seems as someone healthy it looks a bit weird.

The most visible part of this - is the upper part of the nose - the area when it gets to the eye line.
You should practice some facial proportions. I think that you could easily resolve this issue, by conducting some studies in your future works.

But since these mistakes are so small, the observer can notice them only if he/she watches carefully the picture for a long while. The colours are so captivating, and so are the eyes - which might cause one to look on these both parts separately and not to notice the slight problem in linking the two!

Nonetheless I love this work. Well done.
