Nice team ! When I remember my first attempts at painting, this is even awesome. Playing with and against painted teams is so much more fun, and you not only have a painted one, but it is also based, which can make all the difference. Just one hint - player numbers on the base, front and back side !
As for taking pics, there are great tutorials in the web, so I won´t elaborate on the more special stuff. To start with, don´t take pics on the bloodbowl pitch when you want to present minis. Take a neutral (white or light blue) background. Daylight is better for pics than artificial lights. For me overcast sky works better than bright sunshine. Place your camera in a tripod (a book or two would also do) and use the self timer. Try taking pics with and without flashlight.
