I think the plates could be rotated inwards a bit and then add another block to make the inside slope shallower (because this slope would become too steep when you rotate the block inwards)
Also I believe the spike onto of the head should not be flat as it makes nidoqueen look different from the front
Approval now, seriously! awsome work, even the plates are good for me!
Love your work, aren't you officially one of the best here now? Even though it's mostly nidos, can't wait what your next work will be.
I only give advice, take it or leave it.
I did my job, now do yours, a choice.
I'm weird, so don't take me too seriously, I'd feel bad for you.
Unless I say it, I never mean harm, it'd make me look bad if you think so.
