Ah, okay, the items are clean and shiny, but you should render/paint them in the size, that you need finally - I guess you need them somewhat smaller.
An example - made with 3DGS as well, that I like very much, could give you further inspiration:

EDIT:
In case that you aim for commercial success with a casualgame - don't underestimate it - they already got a very high standard, the gamer are accustomed to many bells andd whistles, grafically, although you can overcome this with a unique consistent style.
