You're right, I just looked at your ratios again and it could use a bit more herbs.
Like I said in my edit, I'd probably stick with neutral herbs after you add a bit more spice or maybe even add the spice to the neutral herbs and mix those with your existing.
You definitely have lots of options.
You could break up your existing batch into several smaller batches and experiment with each of those.
That way you have a "control" to look back to and then a few variants.
It just depends on how froggy you're feeling.
