I bet you really mean YOUR first few hubs, right?
Let's see. You joined 5 days ago, so your first hub can't be any older than that. It has reached 70, which isn't shabby for 5 days.
Could it be better? Sure. But I suspect most don't do as well.
Your genre is not my thing, so I only read a few sentences, but you seem to be capable of decent writing, so there is no reason you can't do well.
I suggest seeking out forums where people with similar interests lurk. Chat it up, get to know people, let them know you. Better scores will follow.
