FIRST sketch is free but I make it as I want, with the technique I prefer, taking my time and I do not modify it on request for any reason.
You can use FIRST sketch as you please, there's no copyright, you can pretend you did it yourself, but also can I, obviously.
Any document you send me will be kept confidential and I assure to destroy my copy once the sketch has been made.
A feedback is welcome but non mandatory.
If you agree with my terms you can go to "Get a free sketch" page
You can also ask for OTHER sketches following first free sketch.
