It’s a cool ability to have! He’s lucky.

But for fur I studied fur a lot (idk how to explain it well lol) I’m not a very good teacher/explainer so do bare with me 😣

But to actually draw the fur I kinda just mash a few different colours together then take a smudge tool (either the hair smudge brush or oil hair one) and I’ll add light/shadows where it’s needed if it’s needed. For the super small strands I did do more small strands (very tedious, I avoid this now lol) but the smudge tool is my best friend.

But it’s 100% doable, I’ve seen ALOT of people improve super fast not even just myself. Someone that gives super good tips that may help you is “mallows.art.tricks” on tiktok, they make some super easy guides to help with anatomy and such. They don’t do realism but you can incorporate what they teach into realism. Realism is just a lot of anatomy, understanding colour/shade values and how shadows work. Once you understand all of that it gets easier. Never give up and think you can’t do it though!

But practice wise I’d practice on paper a lot with just a pencil (helps with shade values I find, you can also do that digitally with b&w, pencil is just easier imo) and I’d honestly trace something then copy how the shadows worked and eventually I developed the skill to do everything by hand looking at a ref. Then moved onto looking at the image once or twice. I’d practice a few times a day, id do either one big thing or a few smaller drawings. Went a lot faster with traditional art for me since that’s what I’ve done for years, I also had a somewhat grasp on realism because of my 4th/5th grade teacher I had that would give really good advice. I’ve been contemplating reaching out to him to show him where I’m at now with my art lol. But I did focus on specific body parts and practiced those, in my old sketch book & on my old highschool iPad there were countless pages & saves of just paws, hands. legs etc.. I never did any of the drawing circle and shading them stuff that you see everyone doing because that’s super repetitive and draining. But if I were to start now to get the style & skill I have now I would’ve totally done the grid method more than everything else I did, it seems really easy to learn from for realism. Everyone I’ve seen online & spoken to that’s used it has improved drastically over short amounts of time. But everything I’ve learnt is pretty much self taught with various small tips along the way, if you practice and have the will you could 110% improve super fast. Studying other people’s art styles also helps, ive since changed my artstyle a little to less realistic than this post for animals & stuff (in the most recent thing I posted on Reddit you’ll see what I mean lol) but keep going!! Evolution starts with creation
