Jurassic Derp

My submission for the Newbie Artist Training Grounds V on Equestria Daily. 

The prompt for day 1 was to draw a pony keeping still or holding tight. Here we have ponified versions of Dr. Alan Grant and Lex Murphy from Jurassic Park standing rock solid while facing down a giant Derpy, whose vision, as we all know, is based on movement or something. 

Painted with my finger in the Sketchbook Express drawing application on an LG Lucid smartphone.

Comments are welcome and appreciated.
