I like it a lot! The only thing that would bug me is the -s on the end of [name_m]Thomas[/name_m] running into S- at the beginning of [name_m]Sebastian[/name_m]. [name_m]Thomas[/name_m] [name_m]Clarke[/name_m] [name_m]Sebastian[/name_m]? Or, if you don’t mind putting Thomas in the middle, Sebastian Thomas Clarke has a great sound to it, I think.
[name_m]Thomas[/name_m] [name_m]Sebastian[/name_m] [name_m]Clarke[/name_m] is a handsome name! I love how it combines the classic [name_m]Thomas[/name_m] with the more eclectic [name_m]Sebastian[/name_m] and the unusual [name_m]Clarke[/name_m]. I did notice the S repetition before you pointed it out, but I don’t think it’s a deal breaker. Having one name with three syllables, one name with two, and one name with one gives it a lovely flow.
I like it a lot! I’m not really a fan of the name [name_m]Clarke[/name_m], but somehow it sounds so handsome with [name_m]Thomas[/name_m] and [name_m]Sebastian[/name_m]. I don’t think the double S’s are a big problem.
