Afrovenator's shitty day (Rip Spinophor spikes)

A remake of a drawing requested by someone around three months ago. It's a Spinophorosaurus kicking the ass of an Afrovenator. It took around four days to complete. I feel as if this is one of my weaker pieces, I do like how the perspective turned out though.  3/30/2014, I now just colored it in a bit more so the colors show better.
