Without pics of your mare, all I can do is a paper to paper comparison of their pedigrees. I created a link for the possible foal: Fantasy Khartoon Fantasy Khartoon Arabian
The combo pedigree looks like it would give a sport horse but not main ring off spring. Probably would be athletic but not necessarily main ring pretty. I find KK to be rather coarse and thick in the throatlatch. I would cross a mare with a long neck, fine throatlatch and very typey, even preferably exotic face with tiny ears, if I were to use him. I'd also want a really big eye on the mare, and not any history of 'human eye' because he does pass that on.
Your mare is chestnut and he is homozygous for Black & Agouti which means you will get a bay, there can be no other option. If you're mare is also a sabino or at least not a 'white killer' then you could get the extra chrome that makes people either love or hate KK. I love his color, am not crazy about his confo.
