Overall, i think you need to work with shading. Mainly the drop shadows (is that what theyre called? o.o lol) Have you tried using tissue paper to blend it? I find that it works very well...
wow seriously? I never thought of that b4!
to blend i usually use my finger haha, i have a couple blending tools, but none of them work just right.. i also use a q-tip from time to time!
and ya my shading suck ***! Thanks!! ;D
