Lylejk, I really like the result you have obtained in spite of the lot of effort I imagine you must have lavished.

Regarding your main request, know that I have been searching for years for any software able to transform bitmaps into ANSI art, but without success till now.
On the contrary, as you may have noticed, the opposite transformation is provided by most programs handling the ANSI files, and also you can find several interesting applications which easily allow you to translate a raster image into ASCII art (JavE, Ascgen, etc.) and viceversa.
Anyway, in my opinion, the best program for creating ANSI art at the moment is PabloDraw, not only because it is one of the few that is still developed and regularly updated, but also and especially for the nice graphical interface and the powerful painting tools with which it is equipped, giving the possibility of drawing with mouse, unlike other programs of similar type which enable you to operate only through the much less convenient keyboard.
