You are leaner than 23% for certain mate, how did you measure it? visual? 15% is about right I reckon with your abs definition.
You have a good chest, to really show it off you could develop your shoulders and traps a little more, I would recommend upright rows as these would work both perfectly and in the same movement.
Its all good as it is mate this was just a tweak for future developement
Keep up the good work
