And that derg likely knows a swamp derg

you can see the mud below

You've probably been swamped at least once

^Dunno what the swamp thing is about, but I like the color for the ground first off. Gains the viewer's attention with the grey and colour contrast~
You also draw ferals well :^> I'm still practicing drawing them and they're hard as hell haha x)

Thanks :) I'm still practicing ferals as well. I have most practice with dragons naturally~

the mud thing is an inside joke heh :P

Haha, I should do a feral as my next drawing to post publicly. I've only posted one before over a year ago and it was only a little cartoon and was terrible :^y
But with you, you're very good~ I'd say the thigh muscles could be slightly thicker, and maybe have the arm's triceps connect with the wing-arm's muscles. Possibly the biceps as well. It seems those muscles are connected on their left side though.

But honestly you can't really be wrong since dragons are mythical and honestly it's fair game when it comes to drawing them. So really it's not a problem, it's just by what I observe with other dragon drawings. So maybe something you can experiment with? But overall I think you draw dragons perfectly well. Sorry, you draw better than me yet I'm telling you how to draw dragons xD I really don't mean it in a criticism way :^u

And oh, I wasn't sure if they were mocking you or not haha. Sorry ^ ^;;

good to meet another fellow dragon

well met :)
