In the reference photo you posted the Dad's blue/green eye is much less saturated in color and is shaded quite a bit more than you have painted it. You have also drawn it more wide open than it is in the photo. (The upper eyelid arches up too much.)

Fixing those things will make the difference less apparent -- unless of course you WANT to emphasize the difference in eye color. If that is the case, it will become the focal point of the painting.

Speaking of focal points
 

When there are three in a portrait, do I make one the primary focus or concentrate on three sets of eyes as the center if interest? In seeing it posted here (smaller helps) I think it needs to be less obvious. I'll shade and lower that eyelid as you suggested. Thanks!

I just finished a commission of three kids and I made all three sets of eyes equal in importance.

If I was creating a painting for myself I would have composed something more interesting with one dominant figure, but since it's a commission the parents don't want to favor one kid over the others.

Focal points
 

Its time to get to work now, after working on his eye I'll see where this takes me. Since he is the father and dominant in the picture his eyes may be the focal point, simply because of the coloring. Will be in later. I appreciate your input.

Eyes!
 

I love eyes. Here's the update. Its getting there.

Jean

Oops
 

Don't know where it went, I'll try again.

Dark to light
 

Jean, I am reminded of how we were taught to work from dark to light in oils. In your painting, you worked light to dark. Your reference photos have rich darks which are lacking in your layout. If you were to work dark first, then slowly add the lights, leaving the lightest colors for last, your painting would have more drama.

Trying again

Yeh!
 

Now Nick.

Tom's been messing with the computer all day, don't know what he did but I got an image up!

Jean

It's getting a lot closer. I'm glad you can post images now.

The Dad's blue eye is still much lighter than the brown one. Squint at your reference photo or better still, convert it to monochrome and check the values.

The son's forehead is somewhat overmodeled, though it's much rounder than before. (The forehead needs to have simpler large value transitions, more blended, less blotchy.)

It's coming along nicely. Can we see the whole image?
