Ulog- the first 3hours of my day

This is an artwork that took the first 3hours of my day, it's a charcoal drawing.
My graphite pencils got exhausted and so I had to force myself in learning to use the charcoal pencil and I learnt a few Tricks within those 3hours...one of the tricks is this , learn to be patient when shading, don't rush it or force it. Otherwise, you'll make a mess.
I just left my comfort zone ( graphite pencils ), I hope you do the Same.
