I really hated that glowing eye from the earlier version so I paint in a more conventional eye, choosing a yellow/green hue that will hopefully stand out from the blue/green in the background. I also feel that the background is a little unbalanced, so I use a soft brush to stroke across some of the textures around the edge of the painting to reduce their contrast which should draw the focus more towards the centre, and touch some of the blue from the horizon into the top of the picture in an attempt to balance the distribution of colours a little better.
