good artwork, miles above anything I can do. my only problem is that I don't think the twins were there

Great technical execution and composition, however its hard for me to connect to this piece since a) it lacks context for those unfamiliar with the reference such as myself and b) it's a narrative rather than something of a more self explanatory piece. That aside though, your image structure is great, nice sepia tone and use of shadows and highlights. The characters expressions are also very well done, keep it up!
