Not really my taste either. I'd rather see beautiful woods, but that is just me.
I'm not against subtle embellishments or even full on artistic creations, but sometimes the sparkly, shiney abalone inlay just comes over as a bit gaudy, if its overdone. We have a New Zealand abalone called Paua, I see tons of it washed up on the beach every day and a lot of cheap tourist trinkets are always coverd in it, so for me too much on a guitar makes me think it is trying too hard.
Was not aware Seagull did such custom shop jobs, until I saw this posted on the Seagull Guitar Lovers facebook page.
The guy who owns it is as pleased as punch and that is the important thing.
