What should I put in this? (Patreon)

(you won't be charged for this post)

the picture is included as an attatchment, for some reason a post has to be a poll *or* an image.

So this picture of a containment unit needs a creature in it. Originally it was going to be part of a dragon sequence, but I'm not happy with it. Other people seem to like it however, so rather than throw away two days of work I'm going to run a poll for what I should put in it. Feel free to make suggestions not on the list.

Note that the scale of the scene can be adjusted by resizing what's behind the window, so smaller or larger things are possible.
