I think it looks great - the style is clean and sharp and modern. But would alter to make it look less like a dollar sign. Do not change the font of the writing though. Looks good.
Thank you so much for your feedback do you have any idea instead of "S" ? I really will appreciate your advices
I think that the logo has a "High-class" appeal in itself. I am far from logo design industry (although not that far, web development) but I really appreciate such art. Keep up the good work, you clearly possess quite a talent.
