Illustrator CC logo cleanup and design adjustments! tutorial 2015

In This adobe illustrator CC tutorial we will clean up a logo (we got it this way from a logo design firm for around 100$). The logo has overlapping shapes and the objects are not properly trimmed. Also we are making adjustments using the pen and direct selection tool. The pathfinder and group features are used to merge the shapes. Also smart guides are really helpful to close open path. You can see the logo in action on our department website: http://www.udue.de/leeselab The text in the logo is in german and means "Aquatic Ecosystem Research". Do you like the logo for a genetic research department? Let me know in the comments below! If you would like more information on my research visit http://www.luckylion.de
