Thanks for your comments. I'm glad you like it.
I've posted a thread in the 'Board index ‹ SP-Studio Art ‹ More than just pictures'
section showing it, but I think that here, the gallery, is the right place to put it because:
1.- It is SP-Studio stuff
2.- It is my own user gallery
3.- File size and dimensions are under the specified limits
4.- It isn't offensive at all for anybody
5.- I haven't seen anywhere any rule against it
So... it stays.
