This is a 5 object composition I started working on earlier this evening. Actually I should say late last night since its already 4am. I wanted the perfect night light to get the right shadows. However I was getting frustrated with the sketches and I was to distracted by phone calls from home and the need to surf the internet :-).
Anyway, I think this is enough to server as a pre-production sketch I still need to work on the lighting and shading of more of the object but at least you can get an idea of what I am working on. I have done a few other pencil sketches but will upload them later.
Any comments feedback on how to improve this will be appreciated. I am new at pencil shading so any help is appreciated. I need to look up this great pencil artist. I forget his name right now but I have seen his book and his work is amazing.
