Very good work for an "amateur enthusiast".  :)  I don't think you're using
the stock lens; what are you using?  You're getting great sharpness, I'm
guessing it's an "L" lens.  Several of the pictures are simply lovely:

"photojournalistic" shot, for the poster I was talking to yesterday about
improving their snapshots into photographs.)

This one is gorgeous, but with the caveat that it's a bit greenish,
especially noticeable in the sky.  I'd play with the color balance a little
bit, and then you'd have a perfect shot:

This one is a good shot that's seriously underexposed:

otherwise I'd discard it)

I would discard this one from the collection:

It's a "near miss", but the composition just doesn't work.  The deer's head
is dead center, and the branches that fill the entire left half of the frame
are terribly distracting.  One branch even intrudes onto the deer's face.  I
know you're digging the sharpness of the deer, which is indeed nice, but
sometimes you have to acknowledge that you have a picture that isn't working
as well as you'd like it to.  :)  That's ok, these are actually great
pictures to have sometimes, because you learn the most from your "near
misses", I think.

The others all have merit, and if that's what you can shoot after 2 months,
imagine what you'll be shooting like a year or 5 years from now.  Keep at it
and keep us posted!
