Deutsches Panzer,
I think that the advice you are receiving to stick to a "beginner" kit is sound, and you did ask for our advice. At the same time, I'm presuming that you've been modeling at least in armor for some period of time, so I'd also tell you that, if you see something you want to build and you are comfortable with it, go for it - within reason. But, take your time, be very, very patient, and read up on the "how to's" of both ship-building and any new mediums with which you want to work.
I hadn't built a ship since high school (1980), and only about a dozen kits en toto since then when I pulled Dragon's 1/350 scale VLS AEGIS Cruiser kit off the shelf in the spring of 2013. My wife had bought this for me some years earlier since I'd served in USS Normandy (CG 60). I didn't want to build a "prep kit" first, and definitely wanted to dress her up with AM. I've attached a link to a photo below...was there frustration, mistakes, and a lot of sailor-speak? You bet! Is she museum quality? No way. But I think she turned out pretty well, and I'm happy with the build.

We've given you a lot to think about, but in the end, do what will make you happy...that's what this hobby is all about!
