Momma Rex and Baby

This is a 10x10 ft. pastel chalk drawing I made recently for a local contest it took me roughly ten hours of non stop work (disregarding a ten minute taco break....)and im still sore to this day :/ its primarily based off an old sketch i made a year or two ago, i submitted the sketch but on a different channel i based much of the colors off of felipe-elias T. Rex growth-pattern picture series

I cant tell you how hard it is to get a good picture of such a large piece, so unfortunately i couldn't photograph most of the babies body
