If you throw an outline on the foliage you might actually be able to get away with it.  Yes, leaves can be a nightmare. I feel your pain. :)

Thanks, i truly had no idea on how to handle the foliage.. i've been trying to get it right for more than a year...

I love everything except that the foliage looks diff. than the rest O_o

 The foliage is a lot different from the rest of the piece, try to work more on it to unify the style.
