Just downloaded the pack first time after you started the hospital theme and I'm in awe. Such beatiful assets, so much variations and colors! True work of a profesional :) The only thing that came to my mind is that you could add a sprite for a single cardboard box and single green and pink medicine bottles. It could be used like power ups.
The red chimney I asked also looks amazing!
In conclusion, superb work and thanks for being so active :)
