Technically I'd say they're all bang on in terms of exposure etc.
First one is great in that respect as it really is hard to get 'illuminated mist' type shots right when you're shooting into the light. Impressive too that you've got the detail out of the tree trunks while not totally blowing out the mid tones and highlights (and made it look real rather than gash HDR). I'm guessing it was done in post but personally I consider that to be as much of a skill as the photography its self!
Being totally honest I think it's just the composition of 1 and 3 that lets you down a bit. 2 is good in that respect but would be awesome if you had the lighting from 1 (not that you can do anything about that!!). 1 is OK but the path is a bit distracting and I find it a bit out of keeping with the rest of the shot really. Maybe a few steps forward to get more ferns in the foreground? But then the whole shadow thing gets messed up I guess.
3 I'm not a huge fan of to be totally honest. Exposure/processing wise it's good but in terms of composition I'm not really sure what I'm meant to be looking at? I think it's the yellow tree but theres not really enough separation between it and the background to work like that. I like the foreground detail of the ferns and the background of the misty trees but the middle bit I'm not a massive fan of, it just doesn't bring the 2 other things together well if you know what I mean?
Sorry if I sound super critical, I don't mean to be. Just giving my opinons which may/may not be right! I'm certainly no master photographer by any means at all, but having my work ripped to shreds occasionally has definitely helped me develop my skills.
