The flames are very dim. Fire is quite bright at night.

interesting chop - i agree about the flames , (not emanating light) and the castle is in too much contrast so is not merging very good with the bridge

Interesting work and I like your idea ... agree with the fellows above ... I also might suggest a few less stars and perhaps more variation in size. If you are using PS you can adjust the Scattering of your brush and the variation of size to get a more Star like look. If you need help just PM me.

Thanks for the advise, I agree with them

I tried to fix the contrast, still not sure the bridge works just yet

much better now.... flames in the "eyes" of the castle look identical maybe a tiny liquify fix to make it more realistic

Thanks gornats - know of any good tutorials for the liquify?
