Be wary of Shopina's effect - if you Ash a Maxx C earlier in the turn then you won't be able to use her effect, so if possible it's good to use a light handtrap like Herald of Orange Light. Bloom Harmonist needs both zones free and the Melodious need to be different levels. It also can only summon from the deck and you can only summon Melodious the turn you use it, so this deck is highly restrictive overall. You'll have an extra card drawn and this deck plays a lot of handtraps so hopefully there's multiple of those to back you up, since the field is more about a strong defense than interruptions.
