remember you asked for a critical look
i cant speak to the fit of the bars, that is something i need to see in person and get a feel for. as said , the camera can play tricks on what we see... pens need to be felt to truly appreciated.
as for the photos, i dont think they really do your hard work justice. photos are something we all work at and strugle with every time we shoot one of our pens. your are a bit dark. i too dont like the velvit back ground. I for one dont want anyone saying.... wow great back ground color befor they even look closally at my pens. look at the pics people post here. the ones that are great, really stand out. clean, well lit, no glare..... in your the color shifts as you go back down the pen. it becomes darker and we loose the sense of its ture identity.
OK, I'll end on a good note. for the most part i really like what you have going on. good choose in my opinion for blanks and kits. they seem well finished and professional.. keep it up and you'll go places... maybe even start to pay for all the toys you'll buy funding the madness we call pen turning heaven
