After posting my furbrushes, vines and frost brushes on Deviant Art and then selling some on Renderosity - I would love to find out what Photoshop artsts need or want… Obviously there are enough floral brushes out there that I can’t even fathom why anyone would be lacking. In any case - the kind of brushes I make/create are those that are more useful to people who are into Digital Painting or doing post work on 3D renders. I realize that a lot of people can and will make their own, but if you don’t have the time - paying $5 for a set of brushes is far less painful than spending hours creating your own set.
Let me know what you want, need or would like and I will try and come up with a solution.
My Deviant Art page is here: http://suztv.deviantart.com/
you can download and try out those brushes for free 
- just because I like sharing. And yes - you can use them for commercial purposes, just don’t resell or redistribute them is all.
