Both shots are pretty awesome! But definitely whole different worlds. I'm not sure which one I like more.. They're both impressive in different ways!
Also I think it's cool to experiment with black and white, sometime I'd like to go back and check out what many of my images look like in black and white, it does certainly add a different feel. Cool stuff! Thanks for sharing.
Your right , I feel the same way cause I like both. Not all color shots look good in greyscale. I think you should try and convert some of your images.
