Is the brickwork on the base flat or textured ?
If it's textured, I would darken the bricks and motar. They are very vibrant, almost too cheery, like a holiday decoration.
If it's paper, I would concentrate on making the snow more 3D, at or at least opaque.
The statue base didn't bother me, but the simplest way for you to obscure it is just to bury it in snow. A little bit of filler of some sort, paint it white, and cover it with your snow flock.
