That picture showcases many of the design choices that I hate. The pumpkinhead-ness of it, the fleshy & sinewy details, the tail fin, the hands, its such a watering down of giger's design. It's how the alien became a generic monster.
ADI has talked in interviews about how the fleshy look is a refinement of Gigers creature when it really just strips away all the biomechanical aspects. Now it's just pumpkin head with an elongated head and no eyes.
