#1/Bones: Can imagine your mistaking it for human! Looks well munched.
#2/Squirrel: Very cute. Nice sharpness, colour. Could crop from right ala Rule of Thirds, but fine as is too, so just do it if you want a squarer image for a particular spot.
#3/Bird: Plants draw attention down and out of frame, especially for having such a small strip of them in frame. They're surprisingly bright too - less noticable against the background - but can see why you've perhaps needed to lose some shadow detail on the bird to avoid blowing more foliage. Anyway, main thing for me would be to frame (or hopefully crop) with the bird a bit higher up and more plant matter included.
#4/Deer Bums: Fair enough, but run around next time ;-P. I'm nonplussed by the background - could crop just above the deer for a minimalist (perhaps overly) look.
#5/Lake: Interestingly thin slice of water. The protruberences therefrom - I assume some branches? - are too small, distracting and frustrating. We're left scanning forwards for something to look at. The rock at left draws the eye but doesn't offer much either - a bit more in frame might have helped.
#6/River: Not a fan of the water treatment really, and there's overexposure issues at back, but what I was immediately struck by and do like is the consistent chunkiness of it all: the numerous largish rocks and the many decently thick contrasted tree trunks at back left. That fits in with the robust flow of water too. The crop at top looks a bit harsh and incomplete for not including any folliage - an HDR portrait treatment might have been interesting too.
#7/Mountains: Not enough foreground - pity as the flowers looked adequate, but so marked I'm wondering if you're avoiding something ugly beneath. Bit lopsided/unbalanced by the sheer weight of mountain at left. You've tilted the lens upwards a lot, making the trees at the sides lean inwards - particularly obvious at right. Central mountain's terific and nicely lit: makes me want to be a rock climber.
