I don't know if this is totally threadless style, but I like how it looks.
My recommendation for you is this: learn to hone and pare down. You've got a metric assload of shirts up at Threadless right now, and while there are a handful that are quite wearable, the majority seem really rushed and overly cliched. Take the time to really hone your work down, and you'll see better returns without having to put together such a large portfolio.
