Another broken day passed by Another dead night is waiting to come alive You are already trying to find One more way to hide from the burning light You don't want to see You don't want to feel Nothing but your hopeless destiny
The sky used to be a yellowish color, I have changed to blue so it fits with the image better.
Definitely a nice composition and a good concept. I think what you need to do now is go into the levels of each of the images you have in here and adjust them a bit more until they all feel like they belong in the image. I'd add some orangish highlights to the castle window and adjust the warmth of it in general and that will help bring the piece together a bit more. Using curves or levels in photoshop will help, also using a low opacity brush with the orange of the sunset will help you add those extra highlights.
Thank you for using my stock
