Hi Cassandra! =D Wow, your portrait drawings look really nice! O: Can't wait to see your progress!
As for the Term 1 stuff you've posted, seems like you really have a handle on Photoshop! I think you did the image adjustments and the mountain/forest cabin really well. The dragons flying around the volcano castle doesn't look too bad either, though I feel like... maybe it would be more convincing if you made the mountain into more of a volcano instead of being more mountain (if that makes sense?).
And you can also make better circles if you draw a little faster/with more confidence in your strokes! :] Though I totally get it... drawing good circles is sooooo difficult OTL
In any case, it's really looking good so far; keep it up! =D
