Jen,
Well done! No bad for your early attempts, and certainly better than my first few that I did. (I'll have to dig some up and digitally scan mine so you can compare them.)
If these two images were good cheesecake mine would be certainly have lots of sand in them - yes they are that
grainy.!
In the end you have nothing to be embarrassed about at all!
Ta for sharing them!!
(Might now try some myself too when the weather clears at bit!)
