nice work you need to add shadows to blend imo

i agree with nisha. i like you concept, definitely, but just a few little things i might add... bringing some of the brick texture up onto the face to blend it in better...some shadows and stuff...and then, also, blur the horizon so it gives it more depth. also..and not to be picky, but just trying to help... i think the yellow of the stones going into the water is too bright. perhaps lower the saturation so it blends better with the image as a whole.

Thanks for the comments, I tried to fix must or you suggestions - the bricks on the face are still stumping me though...

You've done a lot of cool work here which would be easier to appreciate if you included an SBS. I'm not sure I agree with the relative simplicity of the foreground/midground against the complexity of the background. The perfectly horizontal panels in the door are at odds with the tilted horizon in the background.

I have to agree with most of whats been said, great concept but a little more work on the blending factors.... best of luck
