Mrow! As someone who's been doing art for years, let me give you my wisdom; don't give up. Your art WILL NOT be what you want it to be at first. No where CLOSE. I used to not be able to draw worth SHIT. And now? I'm very happy with my art.
The point is, keep trying. Becuase you will look at this amazing furry art and think "They're better than me." Don't do that. Look at that art and think "Someday, I'll look at this art and think to myself 'I'm just as good as they are'." And you will. Just keep practicing. Practice practice practice. Never give up. You're gonna want to. Oh, how many times I gave up on digital art. Oh, gods. Too many. Mrrrow, much too many. But I didn't. And now people tell me all the time that they love my art.
Never give up. Keep trying, because you will get there.
As for actual advice, the thing I would suggest is looking up basic human anatomy tutorials, then looking at furry art and trying to mimic it. It's OKAY to maybe try and copy a pose you see online. DON'T TRACE. Use it just as a reference- trust me, it helps a lot.
*purrs* Hope I helped you out a bit!
