Interesting design... I'd like to see some interior renders for this.
I would agree with the Dubai Guys that the "Great Dubai Wheel" would be better situated on or near the Creek. Better views from there and also as it would be seen from the airport it would give a great first impression of Dubai.^^ I think that Dubailand should be built on the Palm Jebel Ali, which will make it more of a unique destination, rather than a theme park in the desert.... Also, the Palm Jebel Ali could have it's own runway/terminal for Dubailand.
With regards to the "Dubai Eye", I always thought Dubailand was the wrong place for it. What are people expected to look at when they get to the top?? A much better location would be wither along the Creek somewhere, or perhaps somewhere along Jumeirah Beach, in either Jumeirah 1 or 2. Alternatively, if Dubailand were moved to the Palm Jebel Ali, the crecent there would make for an excellent location
