Well you certainly have some conflicting elements. It's a little odd to see the back so round and smooth, where the front has a very distinguishable paunch. If you want a flabby berry you generally want to even things out across the whole thing. Either make the whole things round and smooth (or at least to a significant amount) or make it soft and flabby.
the placing of the feet seem to be more in front where the arms seem to be up on the sides. It almost looks like the berry is sitting down, rather than blown up. you may want to move the feet back a ways.
It may just be personal preference but the navel seems a little too large, and the breast may be kind of small. You can argue that some women have breasts near that size without being inflated. Wouldn't you expect a berry full of juice to be bigger?
As far as texture goes, there are several programs out there that will allow you to create your own textures, though I can't think of any that you can get for free/cheap.
