I am guessing the combination will looks good.
Actually i like the whole F row replaced by lyn keycaps illustration.

Other colors why not? If this time is a success run 
We will come out with poll next time.
But to choose one color for all is hard tho.

The mold money is not really major because it can be distributed among the set orders.
It is one-time 25USD only.

Do you mean taking bunny gb as reference?
I wish to offer more colors,
If only people don't mind the price

I hope our community grows even bigger as well.
But to some people keycaps are very expensive, to hit higher tier is kinda hard it seems.
