Nice and modern change, easy to read text on my screen, congrats!! (Still do not like those big badges!!)
You can use images portraits from photodune.com, with a link back to the image, just remove the portrait in the final main file. You cannot use images of celebrities, hope that helps.
Typography has a lot of aspect to it unfortunately it is not just about pairing the right fonts, here is a great article about Creating Exciting And Unusual Visual Hierarchies in Typography http://www.smashingmagazine.com/2013/02/26/creating-visual-hierarchies-typography/
@ muntashir, Don’t compare your designs to the worst designs on graphicriver, instead compare them to the best designs. Unfortunately from what I see, you will need to improve your typography skills and overall graphic design skills, I would recommend studying some tutorials over at http://design.tutsplus.com/
All the best.
You can use the low resolution preview, most times that is enough.
Congrats Chris, keep up the good work!!
