Are you sure they have not made him make it? I mean they seem to pay him in exclusives ;-) (sorry not a fan of his, and he's good at copying a style but if this is him for original work it shows.)
The logo is poor, like someone's first big attempt at illustrator. From a marketing pov how is that colour going to stand out on products? It's a bit faint and bland.
The wings are too robotic in look and movement to look Egyptian or natural.
Probably the worst Merlin coaster logo. Look at wickerman, the smiler and oblivion... iconic and clever. This is worse in terms of design than X:/No way out . I would take quantum, zodiac and vortex of this pile of garbage.
