Need to Take a Photoshop/Lightroom Class

So, I've been messing around with some Photoshop and Lightroom to further my obsession with photography. I took some pics of the kids at various churches and messed around with them... as you can tell, I need to take some classes, because I could not do to the photo what I exactly intended. But still, some came out ok in my eyes.
