Just offering my personal thoughts with the best of intentions.
For me, it looks immediately too busy. My eyes really don't know where to go. This is, in part, due to the card looking somewhat crowded with elements but, also, due to the light and dark blues that really, for me, don't work well together at all.
Yes, you want visual impact, but this is a confused impact.
If you are going to have the light blue in the logo, which I'm not a fan of but that's just personal taste, then drop the Facebook blue and just have the FB link, and website link, in black. That will help a bit because, otherwise, for me, its just a clash.
Concerning the back of the card, not sure that swapping lover the text and bullet point colors in the two columns works. Again, it feels a little overdone.
I think it needs a little toning down, in truth. But, as said, just my personal opinion.
