When working with a client based project just be sure that you are excited about what you are doing. If you are excited about your work, the client will probably be excited about your work, and you will work harder, and create a more interesting project.
Also, be sure to pick your group members based on attitude, and their schedules. If you work best when the sun is out, pick group members that can work during this time.
Keep a positive attitude, and everything will be ok. Take advantage of the time your have to perfect your resume, get as many critiques as you can, and be sure to take advantage of creating a portfolio that works.
