I've been working at it for a few months now- it's not 'finished,' but it's pretty complete. I'm still going to put on a Symphony X official patch, and hopefully get a couple of custom embroidered ones of bands I just need to put on there, but most of the work has been done.
My main influence was HeathenThrone's kutte, it's a work of art- if you haven't seen it already, find it here on Tshirtslayer.
