Death in the water 2 Sound redesign

Ive been working on some underwater comps, this re-design for Death under the water 2, It’s a very short clip, i know, it’s all i could capture. took just over an hour, the most complex parts were the speargun release and the screech of the sirens, no too sure i have completely cracked the dispursed bubbles but im ok with it, any feedback welcome.
