Hey, you must try and find your format. I'm just telling you how I feel about it.

It doesn't have to be "1 image", and if so, it should have a little text at least. But it doesn't have to be dozens, either. For the Netherlands, you could have one post per city, for example. As a musician, it should be no problem for you to film yourself doing one of the hundreds of songs you must know. Nothing fancy, smartphone on a stand, and go... I'm sure you have more songs in your head than countries to travel in Europe, right?

Remember, as you grow, so do your post rewards. Don't blow it all on those low dollar first months. Just enough to be interesting for potential followers. Think about it!
