But whoever looks at your pictures can't see that. What you describe as lack of effort comes across as an easy elegance (And you are a great photographer) and I think you do have an idea what their characters are like, even without a story. It's in the styling. (At this point I have to confess that it was your Doria that gave me the idea about Ruben's ex girlfriend- the beautiful psycho case , so your pictures are open to interpretation).
But maybe it is part of the hobby to see faults in your own dolls and to wish you could create/style/photograph like someone else. I love mine, (and I am very happy you like them) but I am also quite critical. Eyes too large, a little dust sealed in, uneven eyeliner- stuff like that. I sometimes look at them and think I should redo them all. 
There will be more pics of Ruben . But it's already dark at five pm, and I don't like taking pictures with artificial light.
