From last week-- I sent you all the same panel to ink-- I'll add to this post as they come in.

Good linework-- the gray background works BUT you'll need to do something with the characters in the far background-- the face lines are far too generic, even though the original is pretty plain, there needs to be a bit more line variety to sell them. With the background color so gray-- take the two figures in the background to complete black and see what that looks like.
