I specially like the color choices, generally. The guy up top looks good, kinda like Jesus. Shading on top clothing looks a bit pillowshaded, but the pants are ok.
The second guy looks nice, you've enhanced the lineart greatly. The folds on his back are very nice.
The little girls reminds me of Monsoon2d's style, both in colors and in smoothness. Colors are excellent! I think you overdid the external AA though, i'd lighten the colors used so as to not make it so blurry.
Welcome aboard!
