like how abstract we talkin here?

most of the time, you can make some pretty decent logos/designs just out of the shapes photoshop gives you as default
however, if you wanted to get even more detailed, you'd probably have to resort to the pen tool...but i dont know of anyone on this board who has any knowledge at all on how to use that...

so my advice is to jus play around with the shapes, maybe search google and find a few other shape sets if needed...but you should be able to do with what you have
