Hi CHH,
Firstly welcome to the forum and hope you stick with this like the rest of us. You'll soon be serving mouth watering BIR dishes and I would say that you would get from your local BIR, but nowadays a lot of members feel they have exceeded what their local BIR produces! A great tribute to this forum

The crux of of it is, STICK with it. If it doesn't come out perfect on your first attempt then don't worry about it, just keep persevering and perfect your technique for your personal taste. There are a lot of regions/varieties on here and you have to find what suits you best.
Start out with a simple base, you're already on the right lines of where you select your spices, then make a simple dish like a Madras which seems to be your aim, there are plenty on here to choose from.
I would serve this with a simple plain boiled rice rather than an extravagant one, which will allow you to sample your efforts without spoiling them by other flavours.
Then just go from there by adjusting a little at a time until you find your perfection.
There is a lot of experience on this forum to help you in any way you need, so just ask away
