it has potential: you could try to improve some things for the next one: like try to export the mappicture from OCAD (but dont do it HV way, export a tiff and use the tool to export mappictures), or change the ground textures. If you have any questions just ask or send me an email to: color-converter[at]hotmail.com
You can try to change the ground texture a little bit darker and more 'modern' one. I you are able to use OCAD export the map image to JPEG format - at leat 300 dpi - and use it in the conversion.
