Hey David! There are a few options for tablets with displays to check out. Look into XP-Pen, Huion, and Wacom. Each have a range of sizes, display resolutions, and features to meet any budget. These display tablets that let you draw on the screen require a computer running a piece of software like Photoshop, Corel Painter, Krita, Clip Studio Paint, Etc. So the price of those programs (and a computer with enough horsepower to run them smoothly) is something to consider when buying a display tablet. Another option would be to look into an iPad Pro with Pencil, and a program like Procreate for a portable digital drawing solution. Procreate is an inexpensive app at around $20 compared to a yearly subscription for something like Photoshop, etc. so there are a lot of variables to consider. I hope this helps!

You are very good in creating shapes with your values. I liked your first attempt the best. The shapes around the left eye are great. Very architectural. The main problem that I see is that the big shapes are not accurate. The ear for instance is way to small. Is this on purpose? Because it is interesting to look at. If how ever you would like to draw more realistic. The lesson further in the course on measurements would be very useful. But you get there by just following the lessons. Keep up and I am very much looking forward to your progress.
