If you think you want to try your own recipes you should go for it. If your technique is not perfect, that will be okay. Just keep it simple so that if there are faults they will be easier to track down. Make sure you run all the numbers on the recipes you make. When I started making my own recipes I made a Red Ale with Columbus hops, they were super high on the AA and I just threw them all in without running the numbers to find my IBUs, it was a face melter and I'm not a big fan of that. The best tip I can give is to keep track of your BU:GU ratio. BU is bittering units, the same thing as IBU. GU is gravity units, so 1.057 will be 57 gravity units, 1.042 will be 42. I find a BU:GU ratio of .6 to be very balanced, but that is on my palate, you'll have to find your number and orbit around it.
