There's nothing wrong with what you've achieved so far Graf,my Corvette has quite a few imperfections about her too,especially the hull form,but you don't see it unless you're really looking for it. Just take your time,and if there's a part that you're not happy with,then cut it off and re-do it.
I never thought that when I started the corvette that it would end up looking as good as it did.
The only real advice I can give you is,if when reading the article or looking at the plans,you can see an easier way of doing it,then just go right ahead and do it. At the end of the day,it's your model,and if you're happy with the end result,you can't ask for any more.
Keep up the good work
