Yes, he is beautiful. He is a classical tabby, sometimes called also for marbled or blotched tabby. He may have some spots on the tummy, quite a few mackerel and classical tabbies has it, without being spotted tabby for it.
Thanks, StefanZ, Marbled and blotched, that does describe those markings on his side, different than the regular tabby stripes I'm familiar with. It could be the coloration, but doesn't his nose look wide?
