This plugin is really great for easily displaying player heads.
The PlaceholderAPI API is fast.

One small drawback is the inability to display heads in multiple sizes.

It is a very nice plug-in, and I see strong potential for its development.
It needs to be used in conjunction with a resource pack.
Other chat format plugins will not work when using this plugin.
The Github for this plugin also seemed to be preparing support for the PlaceholderAPI.
I am very much looking forward to future updates.

I would like to use the resource, but I only have colorful squares in the chat, even though the resource pack is installed correctly.
