Looks like a pretty good season. Like others have said, cook on it and it should get better.
The only thing I would say about your seasoning is I typically do mine for a minimum of an hour at 400. Use melted crisco as the coating. Let it come back to room temperature slowly on it's own. Maybe length of time is affecting it. If it keeps bothering you, take it to a media blasting place and get it blasted and start over. If it still does it, then I'd think it's something you're going to have to live with.
Personally, I'd just get to cooking on it.
