I too am an appreciator of thicc lasses and I admire that you went for a very specific subject and style. I also appreciate that in your negative you put some effort into stopping the odd skin spots... but that's the worst advert I've seen for NG_DeepNegative_V1_75T. If you are determined to hand-craft I find sometimes the model responds well to 'dirt' as a negative. Alternatively, and at the risk of making it all our work looking super-generic, BadDream, UnrealisticDream and bad-artist may be worth a try.
