Masha's book--Marcia's working sketches

I'm well into drawing my installment of Masha's sketchbook, but I thought I'd give you a progress report by posting a rough sketch of my composition & a tangle of seaweed vignette.  It was indeed a daunting, scary thing to put marks down right on the page next to Masha's delightful, crisp & clean ink drawing. I'm using charcoal & graphite!  I'm working from my photos & memory of seagulls & seaweed strewn on the beach from my recent trip to California.  The gulls are Great Black-Backed Gulls.  The seaweed: kelp.  I hope to post the finished or close to finished work soon.
