Rust Proof!

I recently visited Kyrenia harbour in North Cyprus. Whilst there I noticed this slowly rusting tower. I tried a number of shots to isolate interesting detail. I recognise that the horizon needs to be straightened but do not know enough about digital image correction to make the changes

I'd appreciate constructive feed back.
