For the UK bycatch project, I also had to illustrate some other species than the cetaceans I am so familiar with. Animals with legs and fur and nails... foreign concepts for sure. Jokes aside, it's always a challenge to illustrate a species you don't really know. I always wonder whether a seal or otter scientist would also approve of these, or if mistakes would immediately jump out to them (like they do for me with cetacean illustrations).
I don't really like how the harbour seal turned out, it looks too much like a stuffed animal to me. And the grey seal was a challenge because frankly, those males in real life look like weird muppets. So when drawing you're constantly torn between "does it look weird because I'm messing up or because I'm doing well?" haha. In the end I'm happy with it though! And the otter I'm very fond of. Such keen eyed creatures, I hope to see one in the wild some day.
last year I was swimming around in a little cove in Devon somewhere, and this female grey seal came up to me and we swam together, maybe two or three metres away from one another. I turned blue from the cold because I couldn't leave. I've never felt so alive and special, and I think about her almost every day.
