do you have a background colour in mind or should they be transparent?

The background colours will vary so let's go for transparent please.

Please send feedback!

To be honest, I like all the designs so far! It looks like it's going to be a difficult decision but we'll definitely be selecting one of the options. If anyone else wants to submit a couple more options as well then that would be great ...

oh I just saw that close not able to submit :(
