Triptych Cows

I'm not sure why I'm submitting this, but I guess I just wanted to show you all my artistic origins. I've been using digital media (Photoshop) only for a year since I've always been a self-trained pencil/colored pencil artist. This isn't my best pencil/colored pencil work, but it's something I did sort of recently for my AP art class. It's not a very well thought-out triptych but I have an attachment to it nonetheless, probably because I haven't used traditional media in a while.

Size: about 20" x 30" (i just cropped it a bit)
Media: Pencil for the skull, background is colored-pencil
