There's just too many variables in your problem. Which commercial examples? Then there are only like 300 things that all contribute to those characters. It could be only your recipe if all the others were good to go.
I'd suggest a side by side comparison of the. Write down the top three of four things that are different. Then adjust for that. Could be mash, water, boil, aeration, yeast, temp, etc.
Edit
Are you shooting for a clone, or good drinkable version of the style? Number 2 might be easier and better
