Business Card - Please critique

Hi folks. I know this has been done to death on here, but here are a few rough drafts of my business card for critique. I want to keep it as simple as possible - and I really do like the minimalistic look to the white, grey & black combinations. Do it need more colour? I had thought hard about using some images, but reading other posts on here, the general consensus seems to be that less is more?? Would that be correct?

Also, the "Steven Hanna" part of the logo I wanted to be quite modern and very like a signature. Do you think these fonts work or is there anything else anyone could recommend I try?

Thanks in advance!

Steven

I think I like the last one better as far as the font, but I like the format of the first one. Do you have a studio? If you don't, I would not include your address.

I like the layout but I think it needs a splash of colour!
