Flat Logos - Dragon Shield (WIP)

Had a short notice project come down from Dragon Shield today and I would feel really bad to have to turn them down after they've made my works into an entire line of product. 

That and I really need the funds to put towards my move to a new apartment. I need to get out of this tuna can. 

here are 3 concepts I came up with tonight to give them a bit of choice. I believe I'll have to also do a fully rendered version as well with inks and color. Should still be a fairly quick job if they get their feedback back to me in a timely manner. 

I'm sort of torn between the first 2 myself, which one do you like better?
