Dead-center composition, anyone?

Four-of-many photos I shot for a recent class project: I took a trip to one of my school's biology field stations to gather source images. These are presented "warts and all" as Kodak Max Versatility 400 ISO (Feh!) film in a Pentax K-1000 (Hurrah!) with Tiffen macro lenses (�w00t!) developed at Walgreens on a Fuji processor (Huzzah!) and neg-scanned on an Epson Perfection 3170 Photo (Rawk!) No color correction or dust spotting done. As of this posting, I don't have the species identification available, but can provide it upon request. I (heart) nature.
