Practice kit or not, it looks good. I like to think that my mistakes are what gives my builds a little character. I came to the conclusion many years ago that my skill / artistic ability is limited.
I have improved though with my techniques, but alas it will never compare to what I see here. Truth is it doesn't really matter to me (well not that much), I build to make myself happy. I like what I build, and what you have done with the A4 is awesome.
