Tips and tricks? What does that mean? Tips, well do you know the relationship between ISO, shutter speet, aperture and light? Do you understand how to properly operate both camera and lens without being on full auto all the time?
Do you always use the view finder to frame your shots if your camera does live view? Do you know how to do time (long) exposures for night shots? Can you look at a scene and decide instantly whether or not you need a tripod, longer shutter speed, more ISO?

There's plenty more I could ask but if any of the answers above was no perhaps a photo class would help. There's no tricks to a dslr, just good, clean, photographer skill photography.

Good luck
