The nice thing about ukuleles is that pretty much anything goes unlike guitars where there is such a set pattern. A whale bridge works on an ukulele I think. Probably not so much on a guitar. I say go for it... I notice like it seems that you have compensated the saddle a little skewed to the tenor side. That gets to be a bit of a slippery slope since an uke is stringed up non-reentrant. Depending on your tuning of course. Me, I'm a traditionalist by nature and just use a classical guitar shaped bridge. So boring. In the end I think a bridge is just a bridge. I just want it to do its job and not be a point of adornment.
