The sky is too desaturated. It should have some blue to it, rather than just B&W.

thank you for pointing that out. I slightly colored the sky blue, I wouldn't want to overdo it, as it's supposed to be a dark, rainy night.

Nice idea author....and good mood but demands a bit more work...first thing is if thunder hits sign there would be way bigger spark and lightening there...also u could create a bit softer rain with smaller but brighter rain...sorry for the nit picks...

Nice, but agree with above. The sign looks washed out for a lightening strike, a little more saturation would give it a stronger effect IMHO
