Yep, my sister made a lion using that piece long ago when I got the first Hogwarts castle :O
I think the second arched brick of the front leg doesn't look very good on the lion, it makes the leg look awkward, other than that it looks great.
For a table scrap it's pretty good but I know your standard (you could do a lot better) The legs look awkward. I think you might be on to a winner here, with a few improvements. The following link should help ;-)
First I am Italian-American so I am partial to things with an Italian flavor! Then I am a LEO so I equally am partial to the cat family! This MOC combined both! so how could I give it less then 5 heads!?! Plus it was well made. Now, yes, I have used that lion head piece in my: The Story of SNOW WHITE - Part I - THE STEPMOTHER which can b e found here: http://www.mocpages.com/moc.php/286667 I hope you enjoy it!
