Most of the work I did under the name of RIOT consisted of caricature but occasionally I tried my hand at something else.
Here are some Judge Dredd pages I did with the aforementioned Brendan McCarthy for 2000AD annuals in the late 80's.
I've tried to pick examples where I, at least, can see evidence of my input.
Those who are familiar with Brendans work and have seen the original pages will be aware that I have added very little to the mix.
