In response to Phil's feedback on my previous post, I have re-designed my business card to incorporate all the relevant information on the card's front, and proudly displayed my characters on the back. I'm unsure which of the individual Hydrogen Twins and Oxygen back designs I want to go with, so I have provided two versions of each to choose from. In this case I prefer the Hydrogen twins original landscape orientation pose (HBV2).
I'm not sure if Oxygen's image looks better with him surrounded by white space (OBV1), or whether it works with him filling the card (OBV2)? I've created multiple versions of the business card's front, and have chosen FV2 as my favourite.
