Doctor Doom and Thing Concept Art for FANTASTIC FOUR Movies

Here's a collection of early concept character art for Doctor Doom and The Thing for the original Fantastic Four movies. As you can see the designs are very unconventional, and I don't really like them at all. The movies would have been even worse had they used these designs. I mean no disrespect to the artist, Constantine Sekeris, but I just don't think they work. 

At the time the concept art was made, Nicolas Cage was attached to play Doctor Doom, which would have been interesting to see. What are your thoughts on the character designs?
