Secretworld Environment

Well, i found some sweet art for a game called secretworld and had to do some of the environments from it. The image below is of an early lighting test i have done and first pass on textures. But i am really starting to love the unreal engine and the possibilites of it. The one area i really want to understand is the material editor getting things such as reflections etc but i will also post on here the concept art as well. One thing i have noticed is that mine looks stretched, but this can be fixed later on, it may also be due to the different image ratios i have got! The concept is next to it.
