Definitely needs to be FUNKY... :)
Simple, semi-proffessional yet funky... eye catching
Maybe a little different and quirky? a little out of the box.
My current card has a quote on the front - "Be yourself. Above all, let who you are, what you are, what you believe, shine through every sentence you write, every piece you finish" - this is what made it a little quirky i think
Also I have Spot UV on my card that I love and really makes it stand out.
Company colour is Orange, as you can see in the logo.
I have also had card with 2 rounded corners (opposite) this is liked too.
I am really open to new ideas and designs... i will also be redesigning and updating the website so please dont base your design off that... the new card design will, more than likely, be the basis for the new website design/makeover.
