let's see...
as far as the colours go, looks really nice, though grey isn't nessecarily the colour i'd use for a phoenix as it hints towards ash. a really old, dying phoenix maybe?
anatomically [sorry to say this but it's the truth] it's an epic fail
the crest's design is cool. the wings are nice though perhaps having it smoothed out a bit more would look better. phoenix looks a bit too fuzzy to be a bird at the moment imo.
the torso seems a bit slim. should be wider, i think. however, all that is passable. the legs however are the biggest issue. i'd say ideally, they'd be shorter, smaller overall, and maybe a different colour, but again, colour's more an artist's individual taste. i think the thighs of the phoenix should be a bit more muscular, with the lower legs being slimmer.
the tail seems a bit too saurian, though that could just be the phoenix without it's tail fanned out, like how most birds are when not airborne.
suggestions for improvement [all this is personal opinion. in the end it depends on what you had in mind, not what the critic says

] :
1) make wings sleeker [so it looks more like a bird and less like a plane

], with larger, more curved, individual feathers.
2) Widen the torso of the bird to better accomodate the muscles needed for flight.
3) shrink the legs so that it looks more like a bird of prey and less like an ostritch [i think that might be the primary reason it doesn't sit right with me. an ostritch with wings just doesn't work

]
4) make the beak more hawk or eagle-like, though again, that opinion depends on the artist, and a non raptor-like beak can tend to hint benevolence much more than a hawkish beak
