Thanks every for their valuable comments and suggestions.
YeeWu: Yep, I will need to add the shadow and reflective lighting to take the whole image further. This is where the bright blue reflective light will fall on the city and other objects in the path. Was thinking of applying that in the final colour once everything is in place. It’s good that you picked that up, thanks.
kuzgunoglu: Thanks for the nice comment again. Do your best, its a lot of work in such little time but definitely rewarding to see a final outcome. Keep at it and hope to see your completed work. Do you mean putting on those patch of lines on the new airship I have near the Destiny machine (dome structure) or the red spacecraft up in the air? I’m actually thinking of putting some organic patterns to the red spacecraft, the art nouveau style to make it looks as if it was from another era.
walrus: Red and orange is a very close blend which is difficult to read when it is mixed. But I found the blend of the lights works better if the surface of the building was in this warmer colour, it brings out the whole image alive along with cyan light stream. Though I do agree with your thoughts and will have another look. I still want the spacecraft to have that strong red but will tweak the building contrast. There will also be a slight blue tint as a sight of reflection to hit the surface from that light beam, maybe this will change things. Might also play around with the two other airship next to the Destiny machine (dome structure).
Nathaniel West: The perspective has been quiet difficult to get right, I think I’ll stick to this since I want it slightly slanted to get the dynamic vision of this city along with the strong light beam. The light intensity can be much dramatic but I’m not sure how much more I should really push it, I personally don’t want it to be too hard and have it as a solid form. Though you are so right that all the intensity is on the same level. Maybe the new light reflection of that light beam will sort things out. It requires balance. Many thanks for your valuable suggestion.
