Both cards are nice. The first one, i like how u draw two diagonal lines to make a street, simple enough to connote the idea and the purpose of the club.

For the second one, I like the sense of speed and movement in there. However, 3 lines of texts are not really equally spaced. The last one "Phone..." should be spaced a bit lower. And I guess it should be "Dancing Club", not "Dance Club" right? ^^

Good job Mel ^.^

Your cards are very creative. I like the way you combine Photoshop and Illustrator. I think the second one is better. In your first picture, space of the design looks like be limited by a black boundary.

In the first card, the use of the two lines to create a sense of perspective is great! Little things that detract from the design is your alignment for the address. "Ho" in Ho Chi Minh City should line up with the number "22".

Another things is that the "Saigon Running Club" text is hard to read. Do you really need the gradient?

In the second card, the blur of the flowers is interesting, creating a bit of motion. I'm not so crazy about the "Steps" you've created. It makes the card too busy. Another thing that you have to be careful off is your crop marks. Where you have them currently, the bottom half of "Dance Club of RMIT" would be cut off as well as part of the phone number and e-mail address.
