I'm at the stage of the work now where I hate it and want to tear it into small little pieces and throw it off the roof, stomp on it and mush it into a puddle. I go through this with every painting, so I know it will pass once I get past the "ugly" stage.
All of the above being said, the shading on this one is a killer! The shaded flesh tones are actually shades of grey which one should not use when working a portrait in coloured pencil. Anything but grey. Well, grey and black. Probably purple too;-)
This is the first time I've done eyes that don't actually show any pupil colour. They're all squinty and basically black blobs. This picture sure doesn't do this kid justice!
