I recently commissioned Starbird for a tileset which was a very positive experience! And I totally recommend if you get the chance to!
I also bought the Premium pack on which I can be pretty brief :
The amount of content and quality of work are just amazing.
Also the sheer number of different subjects and themes (and it keeps growing!) is astonishing to see made available at such a price... it's a steal!
If there is any resource pack I can recommend for pretty much anyone it is this one without a doubt!
