After 30 days? Sounds like this is still aging. If it has only been 30 days since it has cleared and you bottled it you are still within the aging process of ANY mead. Give any mead at least 6 months to age, if not a full year.
As far as when my Pumpkin Spice was young, it tasted very spicy but the spices calmed down and blended over time. Did not get much pumpkin flavor out of it and I used 4 pie pumpkins on it for a 5 gal batch.
My Pumpkin Toasted Almond is very bitter, from the almonds and not much pumpkin taste. This one ended up Dry, I think.
The one that is still in the carboy: Pumpkin Hazelnut seems to be very tasty, hasn't cleared yet but a lot of the flavor is from the hazelnut tinture/extract I made and then incorporated into it. I also used the sweet potatoes so I think that I got some more pumpkeny flavor but It isn't ready to be judged yet.
Mead Takes TIME. Be patient with it. ANY mead is going to need to age at least 6 months for good flavors, even a JAOM. I tend to stay away from that style though and use wine yeast and not bread yeast.
Hope it works out for you but I wouldn't expect a bold pumpkin flavor. I am not sure the recipie you used or the quantities but by the sounds of it after full aging you may get some pumpkin flavor but no where near what it sounds like you are looking for.
