Overall, I think that the new design is an improvement over the old one. The color palette is much more attractive than the one used on the current site, and there is much more information clearly presented on the homepage. However, it definitely needs a few changes.
First of all, it would be nice to add a brief summary of this page along with a link to the original. This would be best placed above the features section as a sort of introduction/background to the game.
The features section should definitely be elaborated on more. "Mod Friendly" should have a brief overview of the module system and mention that most of the game's features are implemented through modules, not in the base game. "Forever Free" doesn't really need much elaboration, but adding a couple of sentences to make it match the other 2 in length wouldn't hurt. "Community Oriented" should mention some of the community sites and describe briefly what the interaction between developers and community is like. The name of the section should also be changed, since only the first one can really be called a feature. "Perks" or "Why Play Terasology?" might be better.
The two screenshots used should also differ in some signficant way, since right now they appear to both be screenshots taken of naturally generated terrain using the same generator. Using one screenshot of terrain for the first one then another of a player-made structure for the second one, similar to what the current website does with the background, would be a good idea.
The "Ready Player 1" section could also do with some improvements. The first part of the Developer section is italicized while the corresponding section under Player is not. I'm pretty sure this is an error since it doesn't make much sense for it to be stylized this way. Also, the boldfaced sections should be removed. Most people know what the difference between a developer and a player is, and the illustrations as well as the first part make it very clear what they are. The one for the Developer side is especially redundant since it just says that the developer would want to know how to develop the game.
