Well, I know some people on here aren't familar with animals so I thought I'd make a general "how to" sheet. Note: My anatomy isn't good even with refs. So I'm not the best to look at for that. Also, action lines (motion lines) help some people.
Images refed for the two sketches:
note, I just googled these and didn't use permission. I wouldn't recomment that. There are a TON of stock photo galleries out there. I HIGHLY recommend if your not used to drawing lions or big cats that you get a ref pic of a big cat. (If you can't find a lion, try a panther. Or really any other big cat. To be truthful, house cats have similar positions but not anatomy. But if you jsut need help with the pose, they're fine to ref.)
sorry it's so big. and I hope it helps! If you'd like something like on how to do exspressions or just paws or something like that, let me know!
