Hey Malcom, thank you so much for taking the time! Not at all, I really appreciate the feedback!
I agree on most things - I will definitely use more interesting colours and do another paintover before texturing. You're right, the gills are there in her neck but I'll make them more apparent and maybe add them on the belly. I indeed planned to add scales at certain places. Lastly, I'm not sure about adding armor but I'll think about it!
Thanks again and I'll keep this thread updated Still waiting for some feedback from other places.
