Don't afraid to use references)
You're not a PC, sometimes for drawing you need fastly to see good paws or arm's anatomy or good example of lighting. It's normal.
For productive learning always be curious. if you don't know how to draw something or how to begin >>> just asking it on Google or YouTube, you're not first who have this problem, you just need to find solution.

Good art skill = Practice² * learning * Smart½Stealing * Health

Health is important because, as i said, you're not a PC, your brains is biological machine, toned fresh body = fast brainwork. Bad healthy = unproductive work.
