I'm sorry, Christian, I completely neglected this thread.
I've just listened and examined your work and I'm extremely impressed though. It's sounding very nice now and I can definitely see it as the exposition of a successful love theme. At this point, it's still very mellow and you've done a good job of leaving plenty of room for it to grow both rhythmically and harmonically. You also did a good job of arranging it so that all of the instrumental parts are interesting; you even worked in some double-stops so very nice there too.
So here's the next step: now that you have the initial presentation of the theme in the strings, load up a full orchestra template and copy in your string arrangement. Now we're going to start building the full orchestration from here. I realize that it's quite a jump from strings to full orchestra, but having seen the quality of this arranging, I think you'll manage just fine.
Start small and work your way up - remember that we'll be building upon this as you go, so decide if you want the full orchestra to be playing the theme at the beginning or just the strings? Perhaps you want to move the theme into the woodwinds at the beginning and then add strings only the second time it comes around? And remember that this is only the beginning of your theme: once you orchestrate this beginning section (or decide to leave it as is and orchestrate from here on in), then you'll be expanding from there - perhaps you want a fanfare-style brass statement of the theme, or maybe you want to introduce a secondary theme part-way through.
Don't be afraid to use cross instrumental sections either: have some strings and woodwinds, a brass solo over a low string drone, glockenspiel theme statement with soft woodwind arpeggios backing...have some fun with it. Orchestrate as thickly and complexly as you can because it's good practise.
Feel free to post up any stage of your work as you go and I'll do my best to get to it much more promptly. If you need any inspiration, go back to the examples and take another listen and/or ask in here and we'll work through any difficulties you're having together.
Thanks for your good work and good luck on this next bit!
