These look really cool and I admire that you aim for different styles too.
If something, Seth, M. Bison(Boxer) and Heavy D were the best references for Dudley.

I see you are using MotW torso and new custom pants, he looks a bit wide in the upper part. The obvious way would be to edit the original CvS sprites doing the jacket, erasing the cap and giving him a hairstyle like Ken, Rugal or Rock. It would help you with the stand animation since you simply change the clothes and don't have to make fit different sources as MotW and CvS, I mean in the framecount and arm poses of the final stand.
Nice touch doing a proper star in his shoulder.
