Mm, nice renderings you done there! however i prefer the 2nd image as it's brighter, more vibrant and more living than the 1st one. I think the 1st one is too dark, it looks too artificial and just not real enough in my eyes. The 2nd one is more open and there's just more to see in it.
Good job on them both tho, keep on Maxwelling! ;]
