I personally like the style, for one if the Forerunners where such an advanced civilization why not be able to do some of the things to their bodies and skeletal structures that 343 depicts? They were said to have reached the highest tier of their race according to the cannon. Everything about them could be so different and awe inspiring from anything people would come to expect in them. I do not like everything 343 is doing with halo, but the art styles they are rendering are still pretty superb from what I have seen come from their studios.
