But after practicing for a long time....

[Silverobama]

I once learned how to cook when I was young. At the begining it was very difficult but after practicing for a long time, my cooking skills have greatly improved and I could cook dishes with complicated procedures.

I wrote the sentence "After practicing for a long time, my cooking skills have greatly improved and I could cook dishes with complicated procedures".

I used to cook dishes with simple steps, like fried eggs, fried vegetables, but after practicing, I knew how to cook complicated (multiple-step) dishes, dishes that take time and energy.

Please help me with a better version of the italic sentence.
