Question About a Board i Made

[WiPyro]

I made a board this week first board ive made its got two 40 shot 200g cakes then it goes to a roman candle rack with 60 candles fast visco then a slow fuse to 6 excals then another slow fuse to Big Package 500g. My question is this is all on the same board is it bad to have a candle rack on the same board with my 500g cake they are very close to eachother.

Any Help would be great thanks
