I like it. Product photography isn't really there to be appreciated, it's there to show your customer what it is you're selling so they can make the best decision about whether they want it or not. With so may pens, a border and watermark, this comes across as more of a still life/fine art piece. If I was thinking of buying your pens I'd want to see what the nib/tip looked like.
Putting that to one side though I think the lighting is really nice and as a presentation piece, or headline image as a "starter" for a bunch of single images it works really well.
