That really looks great! I mean the shading alone is great. Ugh charcoal is so difficult for me, it's awesome it turned out great here! :)

I've been learning myself how to do some urinal training by reading tips how to use a urinal online since I haven't use these in years...
The last time I used a urinal since I was 11 years old, I've been using them in my gym latey and I'm pissing in them quite well without splashing anyone with my urine!
I gonna try to use these badboys every time I go to the bathroom can't give up yet!
I know my good urinal manners so that should be okay with me!

Amazing drawing though!
