/ic/ - Artwork/Critique

I drew this awhile back freehand referencing an animal calendar. Any critiques? What to do to make it look better? I've drawn a lot in my life when I was younger, but this was the first thing I've drawn in nearly two years, and this was back in march, I still haven't drawn anything. Anything I can do to get into drawing more?

drew this a couple months back, had a nearly destroyed calendar with a rhino in it from 2002, so i referenced it, i don't really draw often and this was the first thing i have drawn in about two years
I also haven't drawn anything since, bacck in february/march, what do you guys think?

I drew this rhino, referenced out of of an old 2002 worn-down calendar. Haven't really been focusing on drawing lately but did this because I had free time. I thought I did pretty good for a 3 hour time frame.
