I have these growing in my tropical garden in Queensland Australia, and they are magical when in flower like this. I love the color contrast of the red against the green, well done...
I'm not against centering but think, this would have been better off centered. Reds are really hard to photograph and keep looking correct in tonal value. I think you did well up until the very top of the plant. The focus could have been sharper.
I dont think the centered composition works well here, it doesn't add any interest. I also feel the colours are slightly oversaturated on the red since detail is lost at the top of the plant.
