I personally love this picture<3 very original and grabs my attention. I can't help wonder whats happening and why is this girl having her organs sprawled everywhere. It's simple but for some reason it just adds on to it. This would also make a great t-shirt because of the minimal amount of colors used. The style also reminds me slightly of The Binding of Issac but I think the way you did it works quite nicely. My advice to improve are: Nothing O_o I think it's great the way it is. Nothing bugs me. The most I could say is add a mouth but that would take away from the style.... Same with more shading, put in to much and you could lose your whole idea.
just make a journal in your own dA fill it with you favorite arts from anyartist in dA, you can add yours too, and make sure you make it with same theme. so you can add a cool tittle to attract the others to read it ^-^
