Whilst I miss the statue from Parc Disneyland, I think that its inclusion in the Studios is great. Because the park is dedicated to Walt Disney and his movie legacy, it makes sense to have the statue greet you when you enter the main part of the park.
The Partners Statue is located in an area that is currently undergoing a re-vamp. Originally name Production Courtyard, the area is being transformed into Hollywood Blvd, mainly thanks to the construction of The Twilight Zone Tower of Terror.
My only issue with the statue being there is that Walt is pointing towards something - in the Magic Kingdom parks, I get the impression he is pointing over what he has created, as if to say 'Look how far we've come, Mickey!'. But in Walt Disney Studios, when the park was opened, there wasn't really very much there...in my opinion, not that much to be proud of. However, you could interpret Walt in this park as saying 'Look how much we can do here, Mickey!', showing more optimism than in the Magic Kingdom parks.
Talking about comparing Magic Kingdom parks, please take some time to have a look at the fantabulous 5 Kingdoms blog. CheriBibi does a great job looking at the different Magic Kingdom-style parks, with some amazing photos!
