Hey Von, I enjoyed looking through your studies, course work and personal projects; it's a lovely body of work. when I get to this stage, I would love to pick your brains on enviroments and composition.
The image of the lady on the bike with the raven is well rendered, and it's a nice composition. A few things come to mind when looking at it; firstly, be careful when drawing a dark line and dotting both sides rendering the parting of the lip, it will look more natural if you keep in mind the cylindrical form of the lips and gradate from light to dark.
Similar thing with the nose, often, people will go very dark within the nostril, keep in mind not to go too dark.
The details on the bike are great, and the understanding and use of hard and soft edges is spot on. I think the exhaust pipe, again, could use gradual value change to show the volume of the cylinder.
Lastly, this is more of a question rather than critique as I don't fully understand lighting yet; what are the light sources in the background? and would there be any rim lighting on the side of the raven, the back of the figure, and the side of the bike facing away from us? and would those lightsources hit the floor in the background?
All in all, great work, you very much have a style in mind, a great eye for composition and detail. Lovely progress on the course so far
