These are very unique and original designs! The centipede creeps me out a little, not gonna lie.
The crumpled paper design fits together so well with the drawing theme. It looks very balanced overall and the background adds texture and depth. The blurry black and white portrait adds mystery, and is the cherry on top.
The second design is beautiful, but I feel like the color doesn't fit for some reason. Maybe because I'm used to seeing this style of drawing paired with darker, warmer tones like maroon. That may be just my personal experience, though.
All of the little details and embellishments in both layouts are nice touches. Honestly, I wouldn't really change a thing on either design.
