May I suggest cropping out some of the sky? There's not much going on up there and there's quite a lot of it. Some may say that I've only made this suggestion to get my post count up to 500 John
Yes I'd lose some of the sky too and also crop in from the left a touch to lose the chuck of wood in the corner. There is something about the colours that doesn't look right, cant put my finger on it though.
It's a fun shot of a fat looking meerkat. The (what look like) dirty windows and poor weather don't help the picture. I know it adds context to the shot 'cause you know where he is but the dirty flag thing isn't very nice. And yes, looks oversharpened.
