I would honestly recommend focusing on the background first, figuring out the room's overall perspective and scale, and then coming back to the statue. Right now you have oodles of perspective problems. After you've finished the background room, draw the cat statue on top of that in a new layer.
I think they mentioned it was a harsh wip earlier, which makes sense. Definitely looks it.
AS FOR THE STATUE, definitely pick the colors for the room then use those for reflections and shading on the statue itself. For example, orange edge lighting from the fire sconces in the back, whitish-orange underlighting from the light bouncing off the marble, etc.
I'd reccomend leaving the shading of the whole thing until you have that background finished so as to better fit it into the scene!
Also to fix the perspective lower the angle some, there'll be less moving room on the floor but it'll fix the statue looking pasted in!
