Hi Grant... I noticed that 'dratted railing' section too, and it seems to have pushed the larger motifs on some of the other suggested sub finishes around to the front of the tower, which, to be honest, doesn't look so good!
Your swordfish on the other hand looks excellent where it is. So I would say, either leave it off altogether - or find a 'near' location for it if you must have it on the tower somewhere. Cheers, Brian
