It's certainly a good idea.
I sort of envision Thunder Child as being along the same lines as the above, but cruiser-sized, with heavier gun armament (iirc she shot the leg off one Martian fighting machine), probably multi-funnelled. Hmm, yes - watch this space.
I rather like that.A very fine 1st attempt drawing and an interesting subject.I always thought of Thunderchild as probably a Canopus class.
