hello!
I'm not a big fan of keyboard part themed desk mats in general, so for that alone I'm not interested.
If I may throw my 2 cents into the ring though for feedback: having the only visuals of what you want to make as low angle isometric views makes it difficult to see all the details of the design. There is also considerable negative space to the left and right of the design and its just floating in the center of the mat which will usually be where folks place their keyboards and thus at least partially covering it up, though I do see that on mats from time to time so its not too bad if its centered. It also looks like the sizing of the mats in the renders (iso view may be throwing me off) are not the standard 900x400mm mat size. what size did you plan to use for this?
glwic!
