I looked at your image and thought, that's quite a nice icon.
Then I read your post and looked back...
Yeah I wouldn't be happy with the results either if that was supposed to be a wine glass.
There is so much wrong with it I don't know where to start.
But I suppose I can give you a short tip on how to make that better for very minimal effort.
Take your PSD and get rid of the wine in the glass image, merge everything together, select all, copy and then undo back to before you merged and paste, make sure the layer is at the top and then do the following
First- Duplicate the new merged layer 4 times so there are five copies.
In order from top to bottom set the layer blending options as follows.
- Multiply
- Pin Light
- Difference
- Exclusion
- Normal
Then merge the top 4 layers together, select all, copy, undo until you get to the point before you merged the second time and then paste.
Make sure that the new layer is on top and set it to screen and then change the layer below it to linear burn..
Now at least your wine glass doesn't look so much like an icon.
I did that with your wine glass PSD.
Result here.
