I think it looks good, but a 100mm fork is a lot for a frame designed for a 39cm rigid.
Say the fork is 47.5cm a-c, or 44.5 sagged, that means you've reduced the head angle by 5 degrees static and 3 degrees sagged. That's quite a lot. Some folks like that kind of handling, but I'd be in for a much shorter stem to liven it up. Or you could increase the sweep of the bars, which has the same effect on handling as reducing stem length.
