Congrats on your first pin.
Do not go crazy and do a playfield swap or some of the other things suggested on your first game or worry about appearance including LEDs at all.
Play the crap out of it and have fun. Repeat, Repeat, Repeat.
Enjoy it and take is slow so you don't burn out or get divorced. You will meet people who promote both sides of this coin and in my 15 years of serious collecting I have learned not to listen to friends who have no living room or dining room furniture so they can have more pins. Please do not take your wife to any of their parties if you want a second game.
Also don't buy too many before you are ready. That can kill the joy when you feel like you have to fix the car to get to work every day.
Have fun
