The spots don't look too bad to me. Slightly bigger than normal (maybe?), but honestly don't worry about them too much. Overall the design is really pretty and I love it! :3
For someone who is new to genetics you've actually got everything almost 100% right! The only thing missing is the 'A' gene (separate from the albino 'Ab' gene). A tignix needs at least one copy of the dominant (capital letter) 'A' allele for the Sp/Sp 'Cheetah' markings to appear on the fur. Without it the markings are hidden and don't show up (but there's still a chance the cubs could have spots because the Sp/Sp is still in the genetic code). I hope I've explained it Ok for you? ^^;;
Again as you've said you aren't looking to be a breeding artist you don't need to worry too much about the genetics side of things. Like I said this design is gorgeous and I really look forward to seeing more of your work in the future! =^u^= <3
