Firstly welcome!
I find shaving with a cartridge razor more forgiving than using a DE razor. You can get away with pretty much anything and still end up with an acceptable shave. Using a DE blade requires a more systematic approach but when you get it right is very satisfying with an excellent, close shave without the cost and waste of a cartridge.
You might need to experiment a bit with angles. I like a shallow angle almost riding the cap - a bit like brushing the ground with a golf club as opposed to taking a big divot. Plenty of lubricating soap and a light pressure are key.
Learning the direction your hair grows will help a lot - for most people the grain varies across their face and neck but you can feel it by lightly moving your finger tips across your face in different directions. With the grain is where the face feels smoothest. Against the grain is where there is most resistance or roughness. Alternatively you can rub a cotton wall ball over your dry face and notice the 'catch' against the grain.
My best shaves come from 3 passes - with the grain, against the grain and across the grain, but if you aren't sure of grain direction you can start by making a downward pass from cheeks and sideburns, an upward pass from neck and a sideways pass from ears to nose.
Some razor heads are a little bulky making it difficult to access awkward areas like under the nose. You will master these with practice, but if necessary continue to use a cartridge for those areas.
Good luck.
