One suggestion right away: don't describe what user needs to do with words ("tap"). It would look more polished if you, for example, make an arrow that points to those two buttons with just "add media". Assuming you're required to in order to post. If it's not required, just remove that banner entirely, it's too redundant, the buttons are already obvious enough.
@grishka @dansup I disagree, to me it would seem like a button or link then. I like the current way. I think it gets cleaner by making the icons in the banner the same colour as the text.
