I like the all green horizontal one (without the rule) and the all green vertical one. For some reason the black seems to clash with the green for me. They all look really cool and eye-catching though.
I agree that the black doesn't fly with the green, a dark gray might work. I prefer the horizontal ones to the vertical ones but I would give your objects a little more breathing room from the edges and each other.
Clean, interesting. Nice work. I agree with everyone as far as bringing the text in from the edges. I like the typography as well. Overall, I like the last front and the back with all green text. Kudos!
chalsema, thanks! the more i look at it, the more i agree the black needs to go!
morea, consider it done. good idea!
'nubbin(2), I see what you're saying about the edges, are you talking about where the type almost meets the graphic? if so, would you suggest i make the copy smaller? it's already 7 pt. I'll play with it.
you should keep your type at least 3/16" away from the edges of the B/C and you really shouldn't go below 8 pt. on a business card. It looks like you're going for 1 or 2 color printing... consider using a screen of the green at some point in your card to liven it up a bit. Some shops charge more for that, though. Otherwise, looks good.
The text is too close to the graphic, as well as too close to the edges. It would be a little risky having those cards cut, you might end up losing some info. As far as making the text smaller I would try playing with maybe the tracking and stuff, although emails are tough to split that may be a problem.
This something paper reps used to address with their paper sample books. I have many examples of how to achieve this look on press from them. Do you work in print and have vendors you ask for sample?...
