It's great that you have a classical background, I also am classically trained and feel that it really helps me a lot.
Experimentation. Mess with stuff. Since you know what are lfo's, filters and such, it will be easier for you to create the desired sound. Unless, of course you want to use synth presets. EQ-ing, compression and distortion devices are also really important for me. There are no strict rules in electronic music, so whatever sounds good to you is the only thing that matters.
Also, what kind of headphones are you using ? Your music might suffer a lot if you use hi-fi speakers or headphones for production(but I guess you already know that).
