It looks good to me! The composition is excellent, the sky being the prominent part since it’s what the picture is all about. There is just enough of the foreground to add interest, and keep it from being just a “picture of the sky”. The yellows in the sky look a little over-saturated to me.
I notice that the image was shot at ISO 800. Was there any particular reason for that? I generally try to lower the ISO speed, especially while shooting sunsets/rise, since the foreground is always underexposed, and will have to be brightened in post. “Pushing” a picture that was shot at an already high ISO sensitivity will only create more noise. However, I understand, that when shooting hand-held, it’s better to have a grainy clear picture, than a motion-blurred one. In this case, I would have tried lowering the ISO to 200, and see if I could get a usable shot from that. With Canon’s excellent Image Stabilization, you should easily be able to get a blur free image in the lighting you had there. (Of course you could also lower the aperture a little to compensate for the loss of sensitivity.)
I’m also curious, what would you edit in Photoshop, that you wouldn’t/couldn’t have done in Lightroom? 🙂
