Thank you so much for all your very kind words. I really appreciate them!
Your conversions of the figures are very good and you have evolved your original concept into reality very effectively. Using artwork posed in the position you want, as you have done, is a good way to make a start with converting. When sculpting figures I ask my wife to take 360 degree photos of me in the pose I want to recreate, preferably wearing similar clothing. It gives a good idea of the anatomy and the hang of the clothing.
Thank you very much for sharing your hints! I do own some of your figures and I love all of them.
I just can echo what the others have said!
What amazes me most is your ability to change a WW2 subject to a WW1.
It is just amazing! Sculpting is something I sometimes have tried but with less than expected results... 
As far as cutting is concerned I have no problems, but then when it comes to rejoin it seems to me I just obtain a Franklestein-like result 
Do you think it would be possible for you to develop a small tutorial?
What is the green putty you use? I generally use Milliput 2 components putty, but it is very hard to model as it seems to prefere to stick to my fingers and not to the figure...

Hi Edo, I once also used Milliput and didn't like it at all. For larger parts I use Apoxie sculpt and for small details I use this stuff here:
http://www.greenstuffworld.com/en/55-green-stuff .It's also very very sticky and you always have to wetten your fingers and sculpting tools, but then it works fine. I think I know very well what you mean with Frankenstein-likeness. It is often problematic to cut figures into pieces and to reassemble their arms and legs differently posed. I even got problems with mixing arms and legs from different manufacturers. I've got no general solution for such situations besides of going on playing around with different body parts until the result looks right (oh yes, that sounds Mary Shelley-style...!)

Of course I can offer a tutorial, it's an honor for me if you'd like to know how I convert figures. What exactly would you like to know?
are you going to scratch build the lvg c.ii?
This was actually my plan, but at the moment I have doubts. I like the look of the LVG C II too much to destroy a scratchbuilt model of this bird and besides of that I am afraid not to finish this project then at all. As Converting the figures already took quite an amount of time (and I didn't finish that job yet), painting takes very long time and I still have to finish the scratchbuilt Vauxhall staff car. Additionaly scratchbuilding a whole wrecked airplane would take even more time and there are so many kits I'd like to build. I am afraid to have gotten much too ambitious.
Some days ago I ordered another WNW Albatros B II kit. The Albatros C I reconnaissance plane was developed out of that airplane and differs mainly in its front dimensions. If I'd 'smash' these front parts I would "just" have to change pilot and observer's place and to add a gunring to have a crashed Albatros C I. And an Albatros C I would fit well into 1916 and the Somme aerea. E. g. KagOHL 4 used them there. I even didn't exclude the option to built one of my WNW Rolands C II as a shot down plane here. I think to built a kit as a crashed plane is going to be much less work than to scratchbuild it. Since Edo explained me his way to portray damaged canvas covered wings, I wish to try out his technique. It's just so hard to decide which one of these beautiful airplanes I could 'smash', because I don't think I would built this same type soon again as an undestroyed example. And as I already have built a 1/48 Albatros C III, I think I could live with smashing a C I...
