yeah its probably to hard for your first try, there's to many angles. But if you still wanna try, divide the model into separate parts, like the wings do them first, then the engine compartment as another piece. and the nose this way you can focus on each part which will simplify the process immensely, then weld it together. your going to need allot of refs! what version is this? the boxy sharp edged aircraft or the smooth rounded one? there was allot of refs for the smooth rounded stealth version on Google.
your edge flow doesn't look good, it will be a mess with turbo smooth applied, based off a top ref image decide where each section should attach and build clean quad topology based on individual parts and later attach and if necessary add a few loops to maintain quad flow when merging.
idk hard to explain, i would do a simpler model, you'll spend to much time without the experience.
