Hello! You have a lot of stolen images in your Tumblr. You shouldn’t take drawings and use them without asking a permission from the artist first. If I were you, I’d take them down very quick before people started getting mad.
Please don’t take others’ property like that in the future; it’s like you stole their car and parked it in your own yard. I dunno who you are but I assume you’re from TEF because you’ve copied the looks of SmolderBone’s commission blog.
And to answer your question - I’ve studied sighthounds a lot lately. They’re great help when you need to see the muscles in action! :)
