Hi, Nice choice of colours. the eyes are very good and your painting are very neat. The amount of paint seems to be very thick thou and I would suggest to use more thinner layers of paint. This can ofcourse be due to repaiting of the figure and there is old paint still there. Also some more diffrences between shadows and higlight areas is needed. atleast on my computer screen.
The metal areas could use some washes with cold and warm colour to give them more life.
Good luck with your next painting project.
