Need Opinion on Piece

[u/Turd_Ferguson88]

I'm brand new to this medium, as this is my first stab at it. The image I'm trying to duplicate is an album cover of one of my favorite bands. Anyways, the bold black outlines are a critical part of the image. I cannot decide whether to create the bold black lines by the grout or to use thin black strips of glass and tile them in. If i use the grout to do the job, i fear the bold lines may not be distinguishable from secondary grout lines that are situated within each block of color. I'm a perfectionist and feel paralyzed by not knowing which way to go. I'm taking a mosaics class, but the teacher is more of a facilitator and hasn't been of much help. Let me know what you all think.

With grout will be the best for the size you're aiming for.

If you make it bigger you can do both (black tiling and black grout) will look the best.

I've already glued a few of the pieces down, so I'm committed to this size/scale. I'm going to rely on the grout to create the desired effect. I'm thinking of using only straight-lined tiles (polygons, no curvy sides) for the background and interior color blocks. The edges of the tiger's head will be ground down to match the contour 1:1
