No explanation is necessary, my friend. All is good. I only added them again because the control panel said that they had been removed by the group itself, which confused me, and I thought maybe it was some kind of weird glitch. If it had said that you'd removed them yourself, I would have accepted that. Good luck to you.
And by the way, I've looked at your whole gallery, and I see a lot of improvement over time. Don't stop! You are getting better, and as long as you're all right with it I will continue to watch your future submissions.
