Experience

I defiantly like it! This is actually my favourite angle
Although the angle is not the only reason. I must say how great B&W fits this picture. I usually feel pity when people hide beautiful colours of nature under the B&W effect, but that's not the case! We would only see two colours here with a small range of tones here I guess... and they would only spoil the greatness and mystery of the tree. You've done a great job with that shot
