Not probably anthropomorphic people, it wouldn't have much benefits and how could they adapt to society. But they could use genetics to add certain traits such as better vision, disease immunities, lungs capacity etc. But humans genetics manipulating is ethically wrong in many people opinion...
I have drawn only one dragon but I like the art works a lot what people have made. It took about forever to draw one so I haven't done any other this far. Pterosaurs, bats and skyrim were good references.
I have had Huion H610 for three months now, it is my first tablet and I have been very happy with it. Works flawlessly even on Linux. 8"x6.5" for 60$ so the price isn't bad either. I would recommended this device. They can be found from their own webpage huion.com
Reinstall program what you're using and if that doesn't help try the tablet on other computer. Also make sure that you don't have more than one driver installed at once and that your stylus is fulĺy charghed.
I haven't had any problems with Huion but cracked pen because I keep dropping my styluses.
