I know the first one is meant to be dark but I think you need more light on your face, even if its just one side. Also the comp isn't great, there is too much space on the left, would be ok if it was on the right because you would be facing it.
#2 I don't mind but its quite soft and would have been better if you used less DOF and isolated her a bit because that bush and grass doesn't look great. I don't know what lenses you have but invest in a nifty fifty.
