Please don't give up - i'm really in awe of people that do these fan edits, which is why i lurk on these forums!
What you've described sounds really exciting, even if you don't finish exactly like how you planned - it's all good!
I know some people on these forums can be a bit harshly over-critical ignore them and carry on the way you're going!
If any of my comments came across as being negative about your project, that wasnt my intention - I just have a habit of butting into other peoples conversations :)
Since you've started this, it would be a shame not to see it thru to the end!
