Which flat color version of my Godzilla design should be sold on my redbubble page? (Patreon)

I'm planning on selling a few versions of this design, one with detailed shading, and a flat color version. I currently have two versions, one with little scales, and one without, so that would make three designs in total. I thought it would be neat to sell alternate versions of each with japanese text, but that would make six designs in total. I'm no stranger to selling multiple versions of drawings, but I feel versions with and without such a minor detail like scales being the only major difference. So, which one of these should be sold? The version with scales is my personal favorite, but let me know what you think!
