Is it awkward to talk to a girl for the first time on facebook?

So as another female I must say... Most of the time women are bothered by random messages from guys, but if she is also liking your pictures then she must be interested in you. So, you just need to be yourself. Not too flirty, don't compliment her too much. I would honestly just start with a simple "Hey, what's up?" to start it off. If she responds and seems to be engage in the conversation, then it should just be all cruise control from there.
