Very nicely done! These look fantastic and seem to be all done well within the set guidelines. You're sense of form and shadow on the floppy forms homework is very very solid and absolutely conveys a realistic space. The 3 texture study is the only homework I could find any issues with, the first and third feel as though they were less drawn from direct observation and more drawn from memory. Possibly try looking back and forth between your drawing and your reference even more to capture the organic irregularities of the shadows. I do think you did quite well on the tree bark texture though. The texture dissection is alo very well done and they all seem to contour well to the forms too. Fantastic work all around.
