Hi, the first sentence sounds a bit awkward. You can alternatively try, " I can't think of anyone more deserving of (award name), I wish you the best of luck with your nomination!" or "I heard you got nominated for (award name), I'm rooting for you!"
There are probably a million ways to say this in English but I feel like from my experience, " I can't think of anyone more deserving of (award name), I wish you the best of luck with your nomination!" is a great choice.
If you want to keep the sentence short you can just say, "I wish you the best of luck with your nomination!""
