Some stuff for class...
 

I'd like to start posting pictures I draw for my classes to get opinions and advice to better my art.

I think they look good, you've got a good sense of proportion going. What is the medium that you are using? What is your class?

Its pencil on sketch paper, thank goodness no charcoal yet

Very nice work.

Like the brush texture you got there.

was this objective simply observational drawing or is the second picture supposed to imply a deeper meaning as actually the two side by side are quite interesting

This was observational drawing with one light source. The second picture is just the photo finished. Here are the final products which will be turned in for grading tomorrow...don't really know how this teacher grades.
Hopefully will be alright.
