Wow, Ursus! You're already very talented. Those are beautiful pieces. I'm in term 1 as well, and I'm not very experienced at giving feedback, but I'll try to give some. So here goes!
I noticed in the dragon picture that the top jaw is much shorter than the bottom jaw. I'm not sure if this was intentional, but the mouth wouldn't lock correctly when closed. If you're intending to give the dragon an underbite (which actually would be cool-looking, imho), then it isn't an issue of course, but you might want to include a version with the mouth closed to show people what it looks like. :))
In the raven man's picture, it is difficult to tell if he has a cape that resembles wings and feathers, or if those are his wings and feathers. I'm guessing it's the latter. The feathers do not seem much like feathers, so instead give me a cape vibe. Feathers can be tricky to draw, but doing a quick study of a bird's wing would probably help with that immensely.
The second piece is of Minas Morgul, right? I think it has nice contrasts in the colors.
Keep up the amazing work! Good luck on your art journey!
