Heres something for you to look at:
I went to the website where we did get the brushes from. I clicked on the exact brush that was mentioned and followed the website through to a devientart webpage of the owner.
An email address is given on the page and it does not match to either of those given by good fella.
When looking at other designs from this user there are no foliage ones as stated by GOOD FELLA.
The owner is also female.
Here is the website:

Still confused about this and personally not convinced.
