ryanduke, I think that quoted pic (whoever it is) looks good... at least from the front.
IMO There is no universally ideal or perfect fit for anything. What our eyes perceive to be proper and correct fit will differ for each person on each person and may be so for a variety of reasons.
Some people prefer a TIGHT Zathan fit, some prefer a slightly looser Zathan fit, it's about what the wearer finds to be comfortable for him and what people perceive to be attractive ON him. There's also the idea of 'intended' fit and the modification of fit by getting a smaller or larger size to achieve the look that you want or what you deem to be acceptable to you and your environment, culture, society in which you live.
There are some people who I think could go up a size and it would look better and others who I think could go down a size and it would look better, but that is my perception and doesn't make it 'right' no matter how right I may feel I am in my notion.
Indeed some cuts suit certain body types better and some are counterproductive.
