Yes, thats OK with proper credit/link.
@rpm give's us permission to use his logo, and I give the permission to use my creation.
But what is the best way for give proper credit?
(maybe:
'image created by @ctf with logo from @rmp'
or
'created by @ctf and @rpm' ).
I would do it like this:
(image by @ctf and @rpm via: A Steemit Flag)
as well as offer a tip or percentage of post payout
Oh, thats great :)
I will keep it on my list for future use.
see: Welcome to Art-Services for more examples of how I work with artists here on steemit <3
