HELLOOOOO!
I skinned my characters. I have to fix things here and there but it’s working.
I’m trying different poses and now I can’t make up my mind. The third one is the most similar to the original concept…but the first and the second are maybe more dynamic…
However now that non commercial Renderman is out I’m really tempted to use it…
BYEEE
Thank You Tomb! I hope so :/.
After many thoughts, I chose a more dynamic pose.
I’ve started to modeling the environment…then I’ll lighting/shading and texturing everything…If I have enough time :).
BYE!
Little update. This is my last WIP with mental ray.
Now I’m trying vray for the first time (and yes, I’m still experimenting with the pose…).
I would like to add the same mental ray glow effect to the sky but I need to find a way to obtain the same thing in vray…
Mumble mumble…see ya! 
Wow the facial expression is very emotional and moving, the child running towards her too just invokes a lot of emotion for me. Nice love this!
Could just render out a depth pass and use that in nuke to control a glow node, would be better than trying to get glow out of vray, and give you heaps of control
Ayo17 - Thank you so much. This was my purpose :)!
darthfishpaste - Yes, you’re right. I don’t know Nuke at all but I could use something else (however maybe I don’t need this effect anymore).
UPDATE!
This is how my viewport looks like.
And this is a beauty+occlusion comp.
The main thing left to do is the kid’s hair but I would like to improve things here and there…I would like to add more wrinkles to clothes.
BYE!
I like it, though the lens flare >_< I don’t think the sun is bright enough for that big of a flare, feels too forced, might be just me though.
Hi guys, I think that my work is finished :).
This is my final result:
And here a screen of my viewport:
I had so much fun :). May the best win!
Oh my! I’m so stupid guys, I was sure that this challenge would end today!
Since I’ve got some extra time ( -_- ), I worked a little bit more on mom’s suit (I wasn’t totally happy with it). Maybe I’ll fix other things too…
Today I sculpted some pleats and now I think that mom’s suit looks better.
It’s really REALLY hard to make the pleats of the suits pop up with a camo texture like that (If you have any piece of advise :)…).
Nice rendering, mate! 
to make the creases pop up you can eventually add some very rough spec, or lower the contrast on the diffuse…or even better : bring them out from a shadow pass in post-processing
Thank you Nerikson! I’m following your advices. Unfortunately I don’t think that a shadow pass could help me since I’m using a normal map and the creases aren’t “real” :/.
However a good number of friends told me that the background looks unrealistically empty.
The background is empty because my aim was to create a symbolic scene but I’m doing some tests/adding things and the results seem interesting…(I’ll posting something later on).
Hey Marco, you can always add post effects on photoshop, pop some blending mode layers and paint details-in, its easier and cleaner i think, nice work man !
Yes, I think I’m going to add things in photoshop :).
Howeverrrrr, I modeled a house to fill the background (nothing special).
I’m adding other stuff too.
I think that I’m going to blur everthing to get more depth. I’m also experimenting with lights :).
