Thanks all for the comments. So they aren't too dark? I shot with a D7100 for these and they all were hugely underexposed so thanks to Lightroom, I was able to fix this. I increased the shadows to +100 and highlights to -100, set the whites so they slightly clip the edge of the histogram, and set blacks so they also clip slightly on the opposite side. I increased contrast, bumped up the clarity. Using the retouch brush, I painted over the shadows to darken and over the hightlights to ligthen. I've only been photographing for just over a year so this is all pretty new, and I find feedback very useful!
