Well, working from scratch is a bit of a pain in the ass...I mainly work with recoloring stuff.
Do you think you could re-draw this with a few specific changes?
the main changes are this (to make it closer to the loli style), note that I do have help in these judgements, and I do have a slight loli fettish...
Anyways, the chest should be a bit smaller and less defined, lolita clothing alone is VERY constricting and doesn't really offer much in terms of a bustline...
The face is slightly too long, the loli art style would need to be very delicate and rounded off, like a porcelain doll. Depending on the style you're choosing for her attitude, the expression should be very simple.
