The group formed

The new project brief did not publish yet. It is different from the last few projects, we have the opportunity to choose our teammates.It is hard in some way, the last project group mate Spiros ask to form a group with me, then sean, Eric, Pei-chi and yingtao join us. Our group is founded!
the question for us is which brief we goanna take? and for me, the point is which one i can learn more from it and which role i want to take?
