im a noob too so don't necessarily take my word for it but your photos look underexposed. i know you like the darker look which is fine, but there are other ways of achieving it while exposing the shot properly. also it is tough to tell because of how dark they are but check your white balance.
play around with your settings as you shoot so when you download them you can see how the changes impact the shots and choose the ones you really like most.
I adjusted the some...it was a ever hard thing since he was a preemie with jondus he was very orange ...I will work on my exposures thank you for the advice.
