T-Rex Mother and Child

This is a drawing I did as a project for an art class about a year and a half ago. The project was scaling, in which we took a photo, drew a grid over it, and copied that grid to a larger scale on our portfolios. Here I used a promotional image from Walking with Dinosaurs depicting a tyrannosaurus rex mother and its child.

It's taken so long to upload this because, when I got it scanned originally, it was horribly light. The details could barely be made out. I finally tried a few things in my photoshop program Paint.Net and darkened up the features a bit. The results aren't spectacular, but it looks better than if it were whitewashed.

(Note to self: Never use Staples as a scanning service again! You cheapskate!)

Comments and critiques welcome and wanted as always!
