Neat looking Cardinal in the snow !! Didn't see the exposure compensation but could be a little underexposed Check histogram.
For snow the easiest way to expose is to meter on snow and open one and one half stop. The light seemed to be coming from the left side making the right in shadows.... best to have frontal lighting. One other thing is having the bird closer to one of the corners, best area to have a small bird in frame !!! Looking forward to more !!!
Thanks Alfred. I usually err more on the side of not blowing highlights in post, although the original exposure was pretty good. I'll keep the framing in mind for future captures and cropping. I'll post a few more in the next few days.
