Vanitas 29 work in progress

I am working on this drawing: Vanitas 29. I have to finish it and ship it to Arcadia Contemporary before the mid August delivery deadline.

Recently I switched pencils from Staedtler to Mitsubishi Hi-Uni. Boy, am I glad I did! I was amazed to find out how smooth MItsubishi pencils are. They are superior to Staedtler. Now I feel that I can have much wider range of values under control when rendering. The calibration is different from Staedtler, but Mitsubishi has a range as wide as 10H to 10B! I haven't used all of them yet, but I really enjoyed the ones I used so far for being very smooth on the paper and not gritty at all. it is much easier to control the values from very dark to very light. I don't think I would ever go back to Staedtler!
