Tsk tsk! 300mm @ 1/250th!
Don't you know the rule of shutter speed should never drop below your focal length?!
All ribbing aside mate, it's a lovely shot, nice to see some variations in the cropping yeilding some good results - don't let people push you in to overdoing the post processing though, some of the examples on here look dreadful! Keep things natural, it's best to attempt to make them look as natural as possible, think back to how it looked when you eyeballed the scene through the viewfinder, then try to replicate that.
Looks like you've found your feet with your new kit though
*EDIT*
Here's how I'd process them:
Three layers over them:
Colour balance - added more red and a touch more green.
Levels - boosted the midrange to bring out a little more detail ready for....
Curves - Very gentle curves to boost contrast
Finally used the unsharp mask to pick out the detail in the hairs, added a 5x5px border and saved
