You had a lot of good options there at the start. I know there were a lot of similarities between them but still left a decision to be made. For any project like this it's obviously going to be a big and somewhat emotional decision. Anything that you put that much effort into like a record is obviously going to be a work of passion and art so you will want everything to match up for the final product.
Since the album is called Outlier i can see how it all matches up together and think that your cover art is a great fit for the project. Nicely done.
Totally agree mate, Thanks for checking it out!
