Ok, I looked closely at the shots from above, and you are right; some of those colas might be a little close together, but I think if you keep a close eye on things, you will immediately see if there's a problem.
If you can take interior fan leaves that block buds or touch them, like I wrote yesterday, but leave the exterior ones who aren't hurting anyone.
If it gets too close and crowded, consider removing a couple of bud sites to exploit growth of the others. If it's not too close/crowded, leave em. I say that remembering on my sativa grow how I finally arrived at the decision to remove three plants (sob) and leave one, the strongest, so she could take over the grow box. Which she did.
You are keeping humidity down and you have your fan going; I think for a controlled, indoor grow, you are gonna be good. You just don't want leaves laying on leaves or buds.
