Your picture is not showing up. Could you please try and relink it to your flickr account? If you go back into the thread and click on manage attachments, it should give you that option. Thanks
Maybe I can help. Here is the picture from the link:
The pose looks very nice. It seems to be drilling a hole on the tree.
I like the sawdust falling down.
The reds look a little too saturated on my monitor.
The tail looks a little dark. Maybe using flash would have helped here.
Nice picture, like the flying sawdust, overall exposure.
Luis made some good points about the reds, which is a common problem with these guys (easily oversaturated)
There appears to be some luminance noise showing up in the green background.
Please be sure to include all your camera/lens and post processing info, it really helps with the critiques.
From a comp standpoint, I would prefer more room below and less above.
