Thank you very much for the lovely comment!
LOL I thought blocking was like the most obvious choice for geometric element, but I'm glad you like the choice :)
I'm still on the fence about the frame on 11, it's funny that you picked up on that! It was a struggle to find a balance between too dark to be overpowering ands too light to look like it no longer 'supports' the character visually. Idk, it could still use some work, so not my favorite icon here but I'm glad and surprised you liked it! :)
Thank you for all the kind words!
