Noob or not noob ... when you want to talk about a photo you have taken, please present it in the galleries (I now moved the thread to the General Gallery) since The Beginners' Place is a Q&A-forum, ok?
And I don't feel you did anything wrong here, the sky (which is the most important part here) is rightly exposed, and against it the foreground trees HAD to become silhouetted. This is very normal. And I feel the cranes are placed in a perfect spot. With the 50mm lens, you could not have hoped to get any closer to them, but I just like how they are tiny dots in the big, wide evening sky.
Sure enough, the photo offers room for cropping, and if you feel you want to crop it SOME, hm-hm, it might look good. But don't crop in too much, and leave some of the trees at the bottom there.
