Yeah, wow... these definitely aren't noob-ish. First ... these are awesome. I really like the style, subjects, composition, etc.
I'll try to provide some C&C though.
1 doesn't show up for me
2 & 3 both look really good. I think some people might be a bit turned off by the amount of saturation but I personally like them. 2 bothers me a bit though that the mushroom gets cut off slightly on the right.
4. Composition looks great. The only thing I MIGHT suggest is increasing the depth of field to make the water droplets sharp but it's definitely a strong shot as is.
5. Awesome shot... I only wish he / she wasn't cut off on the bottom and the tail at the top.
6. Great sharpness and detail.
7. Another awesome shot. I'm sure it'll make some people cringe due to the subject but that's probably part of the goal.
