That's okay I am studying maths at Uni and have an invested interest in art and maths so anything that combines the two I adore. I think you have amazing artworks. Does that mean that some of them you drew freehand? That's incredable I use a computer program when I make them but I haven't done that in a while all you do is type the maths equation into the program and it shows you what it would be like as artwork.
I think I have rambled as much as you have, though don't worry your interesting enough that it's not so noticable that you are rambling
