Theres no sense of lighting which, isn't giving your piece any form :( decide on where your light source is coming from and that should start helping you out greatly, if you want and i hope you don't take offense by me asking, but do you mind if I do a paint over to show you what I mean, its very quick and rough, but gives a general and better sense of what i'm talking about, besides the lighting as well.

Please, I would really appreciate :) A paint over would definetely help ^.^

Here ya go hun, hope this was of some help, i just tried to fix the general lighting issue and give some blue reflected light since it seems like a night scene, good luck :)

Thank you so much! This will be really, really helpful, since lightning was my biggest issue (imo, at least). I really do thank you, there's nothing more terrible than leaving a picture unfinished, and this will help me avoid that fate :D

Awesome glad to be of help :)
