I'm not sure how much your 8 onions weigh, but my first reaction on reading your ingredient list is what a lot of veg you have for only 8 onions. Videos from restaurant kitchens often show huge stock pots filled with onions and not much more than half a pepper and a couple of carrots thrown on top, so you really have to keep in mind base gravy ingredients should be 98/99% onions IMHO.
Butter is a new one on me, but if you like that flavour in your base then go for it. Have never seen that in another base recipe though.
The bhagar (fried part) doesn't have any fixed rules as far as I can see, just keep it in proportion and remember it's a base so shouldn't be strongly spiced and if it's turning red then you've got way too much tomato. I always tend to look back on videos from real restaurant kitchens and check my proportions are in the right ball park, as the trouble is there's a kind of Chinese whispers effect with people copying someone else's recipe from a forum then making their own changes and over the generations of changes you can end up with quite a departure from what the restaurants are using. An example in my opinion is the way a lot of folks seem to scale down the amount of onions and water to suit a smaller pot but still want to add as much other veg as they saw in that huge pot in the video from the restaurant kitchen.
Like I said, I'm not sure how much your 8 onions weigh, but it seems to me you're making a pretty small batch of base and so "less is more" should be the order of the day to keep the other ingredients in proper proportions.
