That blooms into red and orange.

^ this line is actually 8 syllables! I think.
I mean isn't orange equal to two syllables?

Other than that, I love the way you described the relampago. your descriptions allowed me to see it, and they made me feel like I was there when it happened, in that moment.

Crack of blinding light.
White veins(layer) spreading across skies,
piercing(cut) the dark veil.(COVER)
Cascade(flow) deadly beauty
that blooms in red and orange.

I track all difficult words meaning in your poem, What ever you have written looking nice, just explain me its meaning.

Oooo..now that is a beautiful painting of words! Nicely
done. I was thinking what "Relampago" meant, thanks
for the explanation. Good to read your poem after a long time. Take care and keep penning.
