Length looks nice but can be really inconvenient and I don't recommend trying to get length with natural nails. They break really easy and that can turn really bad if they break wrong and take part of what your short nails would usually be with them. If you want length try some press ons. If you want natural length, don't go very long and keep your tips rounded to make an oval nail as it's much stronger. If you just want more fem, try rings. With that color I'd recommend these.
Just got these in black because I only wear black metals and I love them. Gold with those nails would look fabulous.
