Yesss so nice to finally see you post here, Sovereign

You can already see how much progress you've made with these few pictures. I really like the top 3 pics (the more recent ones) as it seems to me you were trying to take more creative freedom there. Here's some feedback on those specifically:
The Chomper on a rock - this one is really nice. The only bit of feedback I have is that the color of the rock and Chomper's spikes seems to be the same (unless that is not a rock/spikes). Might be a big confusing
The cave scene - not sure if it was your intention, but you've really created your own style here. I personally try so hard to recreate the canon characters that I was never able to do so. It is really nice to see and a really good drawing.
The Guido one is nice too. He seems ready to tackle anything that comes his way

As I said on Discord the only thing I would suggest is making his arm feathers a bit rounder/less spiky.
Keep it coming! Oh and join in the prompts
