Nice first attempt. I like the grain, but Bob Carnie gave me a tip on how to minimize it in lith. He recommended flashing the paper. I never wanted to get rid of the grain so I never tried it!
Very well done, and I like the wrinkles.
From my limited experience, an easy way to control grain is to find the right paper for your taste. When I want grain, I use Kentmere warmtone, otherwise I use Fomatone MG (that's with EasyLith, I haven't used other lith developers).
