Thank you for your feedback. I have submitted the logo on white background. Yes maybe it doesn't have some financial meaning, but the icon of logo is 3d representation of company's name, which is more important in my opinion. And regarding letters, I tried to used different type of fonts for this logo and this font is the best solution, so if I change any letter's look then it won't match with total look of logo. So, as designer I surely can say that the logo is perfect. If you want any changes or have any questions, just let me know please.
Best regards.
Artur
