Newb,
The way you talk it sounds like you are going to quit flying your trainer when your order of the 4* arrives from Tower. I'm going to make a good safe guess, it's probably going to be 2-4 months before you have your 4* ready to fly. Trust me, it's not going to be a week, especially since you haven't built before. Now there is absolutely nothing wrong with this. You get the 4 * in and start building. In the mean time, you fly your trainer until you fly to color off of the covering. From what you have described so far you are no where near ready for the 4*. Yes you may have soloed, but now you need practice. And then after that you need practice. And it wouldn't hurt to throw in some extra practice on top of that. See where I'm going?

I've said in other threads, practice on your trainer until you can fly around your field completely inverted. Please get this experience in before you try to move onto the 4*.

Now with that past us, your work area looks great. Make sure you building surface is flat before you start, you definitely don't want to build a warp into your wings or fuselage.

Hang in there, you're doing great.
